Official description

OpenClaw versions prior to 2026.2.21 contain an improper sandbox configuration vulnerability that allows attackers to execute arbitrary code by exploiting renderer-side vulnerabilities without requiring a sandbox escape. Attackers can leverage the disabled OS-level sandbox protections in the Chromium browser container to achieve code execution on the host system.
