CVE-2026-32977 Details
Description
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.
A sandbox boundary bypass vulnerability has been identified in OpenClaw versions prior to 2026.3.11. The issue arises in the fs-bridge writeFile commit step, where an unanchored container path is used during the final move operation. This flaw allows an attacker to exploit a time-of-check-time-of-use race condition by altering parent paths within the sandbox, redirecting committed files outside the validated writable path within the container mount namespace.
Users are advised to upgrade to OpenClaw version 2026.3.11 or later.
