Postiz lets a signed-in user ask the backend to run a function on one of their connected channels. The backend did not restrict which functions can be requested, so a user could call internal helper functions that were never meant to be reachable from the web interface. One of those helpers reads a file from the server's disk. A user who connects a channel whose stored token is a file path can have the backend return the contents of any file it can read, including its environment, which holds the secret used to sign login sessions, the database address and the credentials of connected services. Another helper makes the backend process exit with a single request. Self-registration is open by default, so no existing account and no action by another user is needed.

CVE-2026-115938 is a high-severity vulnerability in Craft CMS affecting versions 4.0.0 up to but not including 4.18.9, and 5.0.0 up to but not including 5.11.2. It involves improper neutralization of special elements in the template engine, allowing authenticated control panel users to exploit a sandbox bypass in Twig templates. This leads to leakage of the GeneralConfig::securityKey and enables offline computation of HMAC signatures, which can then be used to pass signed parameters to unsandboxed template rendering, potentially invoking native PHP callables.

CVE-2026-115937 is a high-severity vulnerability in the Craft CMS commerce-mollie plugin where the Mollie webhook endpoint fails to verify the association between two attacker-controlled parameters: commerceTransactionHash and id. This flaw allows an unauthenticated attacker with any paid Mollie payment ID from the merchant's account to mark arbitrary transactions as paid, regardless of the actual payment amount.

CVE-2026-115801 is an out-of-bounds read vulnerability in Kakao khaiii versions 0.1 through 0.4. It occurs in the khaiii::nn::Linear::open function within the JSON Config File Handler component. The flaw arises from improper handling of the hidden_dim/class_num arguments, allowing a local attacker with write access to the resource directory to cause an out-of-bounds read. This vulnerability affects unsupported versions of the product and has a medium severity score of 4.8. Exploit code has been publicly released, but exploitation requires local access and the ability to modify the resource directory, which is already a trusted input. The vendor notes that with such access, an attacker can alter analysis results even without exploiting this vulnerability.

CVE-2026-115935 is a high-severity code injection vulnerability in CraftCMS that allows authenticated non-admin users with control panel access to inject a new security key into the .env file via crafted API response headers. This enables the attacker to forge signed login redirects containing Twig system() callbacks, potentially leading to remote code execution. The vulnerability affects CraftCMS versions 4.0.0 up to but not including 4.18.9, and 5.0.0 up to but not including 5.11.2.

CVE-2026-115897 is a cross-site scripting (XSS) vulnerability in the yahoo serialize-javascript library prior to version 7.1.3. The issue arises because the function-source escaping logic fails to neutralize a bare closing-script prefix when attacker-controlled function source text ends exactly at that prefix. This can allow an attacker to inject live HTML elements into a page if they control the serialized function's source text, such as via a spoofed toString() method. The vulnerability has a low CVSS score of 2.1 and requires high attack complexity and partial user interaction. It is fixed in version 7.1.3.

CVE-2026-115895 is a high-severity code injection vulnerability in the capricorn86 happy-dom JavaScript library. Versions from 17.0.0 up to but not including 21.0.4 improperly validate named ESM import aliases, allowing attacker-controlled input to execute arbitrary code in the Node.js host process when enableJavaScriptEvaluation is enabled. This issue is a residual path from an earlier incomplete fix and is resolved in version 21.0.4.

The Arrakis 2026 Autonomous Agents Threat Report reveals that a significant majority of enterprise autonomous agents remain dormant yet retain active credentials, posing security risks. Notably, 76% of agents have not run in 60 days but still have valid credentials and active triggers. Additionally, 24% of dormant agents can be activated externally via unsigned webhooks, and 20% can delegate tasks to other agents with higher permissions, potentially bypassing intended access controls. The report highlights a common operational gap where agent credentials and approvals are not revoked or expired after inactivity, unlike employee access which is promptly removed upon departure.

CVE-2026-115893 is a critical vulnerability in the bytecodealliance wasmtime runtime for WebAssembly on aarch64 platforms using the Cranelift compiler backend. Versions prior to 36.0.19, between 37.0.0 and before 48.0.7, and between 49.0.0 and before 49.0.4 are affected. The flaw allows a user-controlled WebAssembly module to escape the sandbox by exploiting an incorrect conditional branch target when compiling a br_table instruction with more than approximately 256,000 targets. This can lead to arbitrary code execution outside the sandbox. The issue is fixed in versions 36.0.19, 48.0.7, and 49.0.4.

CVE-2026-115892 is a medium severity vulnerability in the Wasmtime runtime for WebAssembly. It involves a type confusion issue where a host-created component-model stream or future can omit a required payload-type check after passing through guest code. This can cause the host to panic when a type-erased value is passed to a guest expecting a different payload type. The issue affects Wasmtime versions from 46.0.0 up to but not including 48.0.7, and from 49.0.0 up to but not including 49.0.4. The vulnerability is fixed in versions 48.0.7 and 49.0.4.
