CVE-2026-32988

Sandbox boundary bypass via raced temporary file creation

Published Mar 31, 2026 · Updated Mar 31, 2026

Sandbox boundary bypass in OpenClaw before 2026.3.11 allows local users to write data outside a validated sandbox path. The fs-bridge staging flow creates and populates a temporary file through target-directory shell paths before the final destination check, so a raced parent-path alias redirects that materialization. Exploitation requires low-privileged local access and precise race timing, and its consequence is bounded to integrity and availability within writable mount scope.
