CVE-2026-43529: OpenClaw: TOCTOU read in exec script preflight

April 16, 2026 (updated May 5, 2026)

OpenClaw’s exec script preflight validator previously validated and then read a script by mutable pathname. A local race could swap the path between validation and read, causing preflight analysis to inspect a different file identity than the one that passed the workspace boundary check.
