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.
