OpenClaw < 2026.4.10 - Time-of-Check-Time-of-Use (TOCTOU) Race Condition in exec Script Preflight Validator

Published May 5, 2026 CVSS 4.0 · 2 Low EPSS < 1% KEV · Not listed
Description
OpenClaw before 2026.4.10 contains a time-of-check-time-of-use vulnerability in the validateScriptFileForShellBleed function that allows local attackers to bypass workspace boundary checks. An attacker with workspace write access can race-condition swap the target file between validation and preflight read, causing the validator to inspect a different file identity than the one that passed the initial boundary check.
