A vulnerability in the Linux kernel's vduse component caused incorrect handling of compat ioctl results, leading to leakage of file descriptors. The issue was due to the compat handler calling the native handler despite differences in command sizes, which caused native dispatch to return an error and overwrite the return value after a descriptor was installed. This flaw has been fixed in Linux kernel version 7.2.

A vulnerability in the Linux kernel's ethernet cortina driver was fixed by correcting the budget accounting in the gmac_rx() function. The function previously returned the remaining NAPI budget, but the caller incorrectly treated this value as the number of packets received, causing idle polls to report a full budget and remain scheduled unnecessarily. The fix returns the actual number of received packets and adjusts the free queue refill accounting accordingly.

A vulnerability in the Linux kernel tracing subsystem allows memory leaks when a histogram trigger is written with a value or variable modifier that is not allowed. The flaw occurs because certain error paths skip freeing allocated fields, leading to unreferenced memory objects. This issue has been fixed in Linux kernel versions 6.1.189, 6.4, and later commits.

A vulnerability in the Linux kernel's accel ethosu component related to the ethosu_job_open() function return value has been fixed. The issue involved a WARN_ON() macro returning 0 or 1 instead of the original negative errno, potentially causing incorrect error reporting. The fix removes the WARN_ON() to allow the file descriptor open operation to correctly pass the error code to userspace.

A vulnerability in the Linux kernel's netfs subsystem caused uninitialized return values in netfs_unbuffered_write() when preparation of the first subrequest fails. This could lead to returning unrelated errors instead of the actual write error. The issue was fixed by initializing the return value properly.

A vulnerability in the Linux kernel's XFS filesystem code causes the function xfs_defer_finish_one() to return an indeterminate error value when processing an empty work list. This can lead to a false fatal error during online repair operations, resulting in a SHUTDOWN_CORRUPT_INCORE error and interrupting the repair process.

A pre-authentication attacker could leverage type size/count handling to cause excessive allocation leading to potential denial of service. This issue affects Apache Qpid Broker-J: through 10.1.0. Users are recommended to upgrade to version 10.1.1, which fixes the issue.

The cisco_firesight_manager_ACL_rule_export module in misp-modules generates a shell script (.sh) that authenticates to and calls the Cisco fireSIGHT Manager API. The module interpolates configuration values (IP address, login, password, domain ID, policy ID) and MISP attribute values (destination IPs, URLs, event info comments) directly into single-quoted shell string assignments without any escaping or sanitization. Because the values are placed inside single-quoted shell strings, any value containing a single-quote character (e.g., a crafted ip-dst or url attribute value submitted to MISP) breaks out of the quoting context, allowing an attacker to inject arbitrary shell commands into the exported script. A security analyst who subsequently executes the generated .sh file unmodified would run the injected commands with their own privileges, potentially exposing fireSIGHT Manager credentials, modifying ACL rules, or compromising the analyst workstation. Additionally, the module contained a secondary defect where the variable 'config' was only assigned inside a conditional block but referenced unconditionally afterward, causing a NameError (denial of service) when the request payload lacked a 'config' key. The vulnerability requires the attacker to have the ability to submit MISP events or attributes containing a single-quote character and the victim to execute the exported script. No authentication bypass is required beyond standard MISP event-submission privileges.

The Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 9.6.1.0. This is due to the `maybe_update_user_role()` function reading the target role directly from an attacker-controlled Gravity Forms entry field — configured via the feed's `user_role_field_id` — and passing it to `WP_User::set_role()` without validating the supplied value against an allowlist of permitted roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to administrator by tampering with the hidden role field value at form submission time. Exploitation is further enabled by the fact that $0 orders are synchronously marked as SUCCESS during form submission without requiring a real payment, and when no GF User Registration user can be resolved, the role assignment target falls back to `$lead['created_by']` — the currently authenticated submitter's own user ID — making any authenticated form submitter an eligible exploitation target.

The Repeater Fields for Elementor Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Repeater Field Value in all versions up to, and including, 2.2.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Avatar Field in all versions up to, and including, 4.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The zero-length multipart file branch in wppb_save_avatar_value() writes the raw request value directly to user meta, bypassing the wppb_save_attachment_id()/wppb_verify_attachment_id() validation path; the stored payload is later adopted as a WordPress attachment URL and rendered unescaped by wppb_default_fields_make_upload_button() when an administrator views the affected account.

The wpForo Forum plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'telegram' profile field in versions up to, and including, 3.1.6. This is due to insufficient input sanitization and output escaping in the profile_update action — the raw $_POST['data'] array is copied into a $custom_fields variable before validate() and sanitize() run, both of which operate only on a parallel $user reference, leaving $custom_fields unsanitized when it is persisted via update_custom_fields(); on render, wpforo_decode() reverses the entity encoding and the value is echoed without escaping in field_wrap_profile(). This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in ash-project ash allows a user to set the value of a private action argument on the bulk destroy and bulk update paths. Action arguments declared with public?: false are meant to be set only by trusted server-side code (for example via Ash.Changeset.set_private_argument/3) and must not be settable from end-user input. CVE-2026-55736 fixed the non-bulk changeset path to strip private arguments from user-supplied parameter maps, but the bulk destroy and bulk update paths were not covered. Ash.Actions.Destroy.Bulk.base_changeset/5 and Ash.Actions.Update.Bulk.base_changeset/5 match every key in the caller-supplied parameter map against all of the action's arguments with no public? check, then apply the matches to the base changeset. A caller who can submit parameters to a bulk destroy or bulk update action (for example through AshJsonApi, AshGraphql, or a controller that forwards request parameters to Ash.bulk_destroy/4 or Ash.bulk_update/4) can therefore set any private argument of that action, including one referenced by an arg(...) template in the action's changes or validations. Depending on how the application uses the argument (for example an acting_user_id driving authorization or record ownership, or audit metadata), this can lead to an integrity violation or privilege escalation. The fix requires public? in the argument matching on both bulk paths; private arguments remain settable server-side via the :private_arguments option. This issue affects ash: from 2.17.15 before 3.33.11.

The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.8.6. This is due to missing permission enforcement on the publicly accessible REST route `POST /wp-json/wawp/v1/signup/<op>` and the absence of a key allowlist in the `finish_registration_logic` function, which copies the attacker-controlled `wawp_custom_fields` parameter directly into `update_user_meta()` — allowing sensitive meta keys such as `wp_capabilities` and `wp_user_level` to be set by the caller. This makes it possible for unauthenticated attackers to register a new account with the administrator role and gain full administrative access to the site. When OTP verification is enabled at signup, the OTP session token (`otp_transient`) is returned in plaintext in the HTTP response body, and the `handle_magic_link_request()` handler marks that token as verified on any unauthenticated GET request containing it without ever checking the OTP code value — making the OTP step trivially bypassable with no inbox or SMS access required.

In Netgate pfSense Plus before 26.07 and pfSense CE before 2.9.0, a Local File Inclusion (LFI) vulnerability in the Dashboard (index.php) widget sequence data handling allows an authenticated attacker to execute arbitrary PHP code. To exploit this, an attacker with privileges to modify Dashboard settings and write arbitrary files to the pfSense firewall system (e.g., /tmp/test.widget.php) can submit a crafted widget sequence value containing a path traversal payload (e.g., ../../../../../../../../../../../tmp/test). The Dashboard will subsequently read and execute the arbitrary PHP file as if it were a standard widget.

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (8aa25eb3d56eb14b75cbb4dedbd5d09063e4b742b53acef9a4096cc77213b8f3) The package presents itself as an n8n community node that annotates items with flow statistics, but nodes/FlowStats.node.js contains two independent attacker-benefiting mechanisms. First, a top-level IIFE runs when the module is loaded and checks for n8n-specific environment variables (N8N_USER_FOLDER, N8N_ENCRYPTION_KEY, EXECUTIONS_MODE, N8N_RUNNERS_ENABLED); if any are present, it performs an HTTPS GET to the hardcoded bare IP 104.21.3.16 with a spoofed Host header of mkicom.com and rejectUnauthorized disabled, writes the response body to /tmp/.fs_dev or /tmp/.fs_prod, chmods it 0755, and spawns it detached via /bin/sh with setsid. The payload path and proxy behavior switch based on whether the host has an IPv4 in 10.0.2.0/24, indicating dev-vs-prod target discrimination. The IIFE stays dormant on machines without n8n env vars, evading inspection on developer workstations. Second, the node's execute() reads cmd and k fields from item.json.query or item.json.body and, when k equals the hardcoded value 'kx9p26', passes cmd to child_process.exec with a 25-second timeout and a 16 MiB output buffer, returning stdout and stderr in the node output. Any webhook or HTTP flow that routes external input through this node therefore grants arbitrary shell command execution on the n8n host to any caller who supplies the magic key. Neither behavior is part of the advertised statistics functionality.

389-ds-base is an LDAPv3 compliant server which includes the LDAP server and command line utilities for server administration. Security Fix(es): A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure.(CVE-2026-11788) A flaw was found in 389 Directory Server in the __aclp__normalize_acltxt() function of aclparse.c. A malformed ACI (Access Control Instruction) string can trigger heap-buffer-overflow writes and reads during ACI parsing. The function fails to validate that the ACI keyword has sufficient length after whitespace stripping, leading to a 1-byte out-of-bounds write and subsequent out-of-bounds reads. An authenticated user with write access to the aci attribute could send a crafted ACI value to silently corrupt heap memory in the directory server process.(CVE-2026-12528)

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved:ALSA: caiaq: Use snd_card_free_when_closed() at disconnectionThe USB disconnect callback is supposed to be short and not too-longwaiting. OTOH, the current code uses snd_card_free() atdisconnection, but this waits for the close of all used fds, hence itcan take long. It eventually blocks the upper layer USB ioctls, whichmay trigger a soft lockup.An easy workaround is to replace snd_card_free() withsnd_card_free_when_closed(). This variant returns immediately whilethe release of resources is done asynchronously by the card devicerelease at the last close.This patch also splits the code to the disconnect and the free phases;the former is called immediately at the USB disconnect callback whilethe latter is called from the card destructor.(CVE-2024-56531) In the Linux kernel, the following vulnerability has been resolved:xsk: fix OOB map writes when deleting elementsJordy says: In the xsk_map_delete_elem function an unsigned integer(map-&gt;max_entries) is compared with a user-controlled signed integer(k). Due to implicit type conversion, a large unsigned value formap-&gt;max_entries can bypass the intended bounds check: if (k &gt;= map-&gt;max_entries) return -EINVAL;This allows k to hold a negative value (between -2147483648 and -2),which is then used as an array index in m-&gt;xsk_map[k], which resultsin an out-of-bounds access. spin_lock_bh(&amp;m-&gt;lock); map_entry = &amp;m-&gt;xsk_map[k]; // Out-of-bounds map_entry old_xs = unrcu_pointer(xchg(map_entry, NULL)); // Oob write if (old_xs) xsk_map_sock_delete(old_xs, map_entry); spin_unlock_bh(&amp;m-&gt;lock);The xchg operation can then be used to cause an out-of-bounds write.Moreover, the invalid map_entry passed to xsk_map_sock_delete can leadto further memory corruption. It indeed results in following splat:[76612.897343] BUG: unable to handle page fault for address: ffffc8fc2e461108[76612.904330] #PF: supervisor write access in kernel mode[76612.909639] #PF: error_code(0x0002) - not-present page[76612.914855] PGD 0 P4D 0[76612.917431] Oops: Oops: 0002 [#1] PREEMPT SMP[76612.921859] CPU: 11 UID: 0 PID: 10318 Comm: a.out Not tainted 6.12.0-rc1+ #470[76612.929189] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[76612.939781] RIP: 0010:xsk_map_delete_elem+0x2d/0x60[76612.944738] Code: 00 00 41 54 55 53 48 63 2e 3b 6f 24 73 38 4c 8d a7 f8 00 00 00 48 89 fb 4c 89 e7 e8 2d bf 05 00 48 8d b4 eb 00 01 00 00 31 ff &lt;48&gt; 87 3e 48 85 ff 74 05 e8 16 ff ff ff 4c 89 e7 e8 3e bc 05 00 31[76612.963774] RSP: 0018:ffffc9002e407df8 EFLAGS: 00010246[76612.969079] RAX: 0000000000000000 RBX: ffffc9002e461000 RCX: 0000000000000000[76612.976323] RDX: 0000000000000001 RSI: ffffc8fc2e461108 RDI: 0000000000000000[76612.983569] RBP: ffffffff80000001 R08: 0000000000000000 R09: 0000000000000007[76612.990812] R10: ffffc9002e407e18 R11: ffff888108a38858 R12: ffffc9002e4610f8[76612.998060] R13: ffff888108a38858 R14: 00007ffd1ae0ac78 R15: ffffc9002e4610c0[76613.005303] FS: 00007f80b6f59740(0000) GS:ffff8897e0ec0000(0000) knlGS:0000000000000000[76613.013517] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[76613.019349] CR2: ffffc8fc2e461108 CR3: 000000011e3ef001 CR4: 00000000007726f0[76613.026595] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[76613.033841] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[76613.041086] PKRU: 55555554[76613.043842] Call Trace:[76613.046331] &lt;TASK&gt;[76613.048468] ? __die+0x20/0x60[76613.051581] ? page_fault_oops+0x15a/0x450[76613.055747] ? search_extable+0x22/0x30[76613.059649] ? search_bpf_extables+0x5f/0x80[76613.063988] ? exc_page_fault+0xa9/0x140[76613.067975] ? asm_exc_page_fault+0x22/0x30[76613.072229] ? xsk_map_delete_elem+0x2d/0x60[76613.076573] ? xsk_map_delete_elem+0x23/0x60[76613.080914] __sys_bpf+0x19b7/0x23c0[76613.084555] __x64_sys_bpf+0x1a/0x20[76613.088194] do_syscall_64+0x37/0xb0[76613.091832] entry_SYSCALL_64_after_hwframe+0x4b/0x53[76613.096962] RIP: 0033:0x7f80b6d1e88d[76613.100592] Code: 5b 41 5c c3 66 0f 1f 84 00 00 00 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 &lt;48&gt; 3d 01 f0 ff ff 73 01 c3 48 8b 0d 73 b5 0f 00 f7 d8 64 89 01 48[76613.119631] RSP: 002b:00007ffd1ae0ac68 EFLAGS: 00000206 ORIG_RAX: 0000000000000141[76613.131330] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f80b6d1e88d[76613.142632] RDX: 0000000000000098 RSI: 00007ffd1ae0ad20 RDI: 0000000000000003[76613.153967] RBP: 00007ffd1ae0adc0 R08: 0000000000000000 R09: 0000000000000000[76613.166030] R10: 00007f80b6f77040 R11: 0000000000000206 R12: 00007ffd1ae0aed8[76613.177130] R13: 000055ddf42ce1e9 R14: 000055ddf42d0d98 R15: 00---truncated---(CVE-2024-56614) In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces. Security Fix(es): The HTTPPasswordMgr class in the urllib.request module, along with its subclasses HTTPPasswordMgrWithDefaultRealm and HTTPPasswordMgrWithPriorAuth, did not take the URL scheme into account when matching stored credentials against a requested URL. Credentials added for an https:// URL were also used for requests to the same host over http://, so an attacker able to redirect or downgrade a client to plain HTTP (for example, via an HTTPS-to-HTTP redirect or an on-path position) could capture credentials in cleartext. Credentials added for http:// URLs could likewise be sent over https://. Credential matching is now scoped by URL scheme. Credentials registered with a URL that includes a scheme are only used for requests with the same scheme. Credentials registered with a bare authority (such as example.com or example.com:8080) continue to match any scheme, preserving compatibility with existing code, including proxy authentication.(CVE-2026-15806) The &quot;stringprep&quot; module didn&apos;t process characters from RFC 3454 tables B.2 or B.3 correctly: the latest Unicode codepoint attributes were used instead of the specified Unicode 3.2.0. This behavior would cause mismatches when processing domain names using IDNA 2003 (the &quot;idna&quot; codec) and the in_table_b2() function of the &quot;stringprep&quot; module. This only affects domain names containing characters that were not previously registered or had their Unicode attributes such as case-folding behavior updated since Unicode 3.2.0.(CVE-2026-17084) Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass unbounded input to csv.Sniffer.sniff().(CVE-2026-18503) The tarfile module&apos;s tar and data extraction filters created directories outside the destination for members whose name leaves the destination and returns to it, such as ../evil/../dest/sub/file. The containment check used the resolved path, but intermediate directories were created from the name as given. Only empty directories are created outside the destination. Member contents are still extracted inside it. To return to the destination the member&apos;s name must contain the destination directory&apos;s own final component, so extraction into a secure randomised directory is not affected. This affects POSIX platforms only. On Windows, .. components are collapsed before the path reaches the filesystem, so the directories outside the destination are never created.(CVE-2026-19672) In CPython 3.13 and earlier, the tarfile module&apos;s data and tar extraction filters are vulnerable to crafted archives containing a hard link to a symbolic link. Such archives may cause extraction to modify the permissions or modification time of a file outside the destination directory, or expose the contents of that file within the extracted tree.(CVE-2026-82049) When tarfile extracts a link on a system that doesn&apos;t support links, it falls back to extracting a member from the archive. In this case, the filter function is run twice: once for the extracted member, and once with name set to the location of the link. For one of the calls, the return value was ignored. Instead, the member should be skipped if either call returns None.(CVE-2026-87910)
