Description
OpenClaw before 2026.3.8 contains a path traversal vulnerability in the skills download installer that validates the tools root lexically but reuses the mutable path during archive download and copy operations. A local attacker can rebind the tools-root path between validation and final write to redirect the installer outside the intended tools directory.
Analysis
OpenClaw before version 2026.3.8 allows local authenticated attackers to write files outside the intended tools directory through a time-of-check-time-of-use (TOCTOU) path traversal vulnerability in the skills download installer. An attacker with local access and low privileges can rebind the tools-root symbolic link or path between the initial validation check and the final archive extraction, causing the installer to write malicious files to arbitrary locations on the system. …
