CVE-2026-40931 Complete Bypass of CVE-2026-24884 Patch via Git-Delivered Symlink Poisoning in compressing

Compressing is a compressing and uncompressing lib for node. Prior to 2.1.1 and 1.10.5, the patch for CVE-2026-24884 relies on a purely logical string validation within the isPathWithinParent utility. This check verifies if a resolved path string starts with the destination directory string but...

Claude Code: Sandbox Escape via Symlink Following Allows Arbitrary File Write Outside Workspace

Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote to the target location outside the workspace...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack via the setkey and unsetkey functions. An attacker can overwrite arbitrary files by creating a crafted symbolic link that is followed during a cross-device rename fallback. PoC python import os import sys import tempfile...
