Last modified

CVE-2026-43529 is a low-severity vulnerability rated 2.5/10 on the CVSS scale. 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.. EPSS estimates a 0.08% chance of exploitation in the next 30 days.
