OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in fs-bridge staged writes where temporary file creation and population are not pinned to a verified parent directory. Attackers can exploit a race condition in parent-path alias changes to write attacker-controlled bytes outside the intended validated path before the final guarded replace step executes.
