Last modified

CVE-2026-32977 is a medium-severity vulnerability rated 5.8/10 on the CVSS scale. OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in the fs-bridge writeFile commit step that uses an unanchored container path during the final move operation. An attacker can exploit a time-of-check-time-of-use race condition by modifying parent paths inside the sandbox to redirect committed files outside the validated writable path within the container mount namespace.. EPSS estimates a 0.08% chance of exploitation in the next 30 days.
