JLSEC-2026-805 Apache Arrow: Potential use-after-free when reading IPC file with pre-buffering

Use After Free vulnerability in Apache Arrow C++. This issue affects Apache Arrow C++ from 15.0.0 through 23.0.0. It can be triggered when reading an Arrow IPC file but not an IPC stream with pre-buffering enabled, if the IPC file contains data with variadic buffers such as Binary View and String...

JLSEC-2026-804 Deserialization of untrusted data in IPC and Parquet readers in the Apache Arrow R package...

Deserialization of untrusted data in IPC and Parquet readers in the Apache Arrow R package versions 4.0.0 through 16.1.0 allows arbitrary code execution. An application is vulnerable if it reads Arrow IPC, Feather or Parquet data from untrusted sources for example, user-supplied input files. This...

Arbitrary Code Injection

Overview n8n-workflow is a Workflow base code of n8n Affected versions of this package are vulnerable to Arbitrary Code Injection via crafted expressions using arrow functions in the expression. An attacker can execute arbitrary system commands by bypassing the intended sandbox restrictions. Note...

GHSA-GV7G-JM28-CR3M n8n: Expression sandbox escape via arrow-function bodies enabling command execution

Impact An authenticated user with permission to create or modify workflows could abuse crafted expressions using arrow functions to bypass the expression sandbox, triggering unintended system command execution on the host running n8n. Patches The issue has been fixed in n8n versions 2.31.5 and...

Twig: Sandbox state regression in deprecated internal wrappers in `src/Resources/core.php`

Description The 3.26.0 source-policy hardening changed the signature of CoreExtension::checkArrow to take a boolean $isSandboxed instead of an Environment, and added the same $isSandboxed argument to CoreExtension::arraySome and CoreExtension::arrayEvery. Compiled templates were updated to pass t...
