CVE-2026-27545

Command approval bypass via parent symlink rebind

Published Mar 18, 2026 · Updated Mar 18, 2026

Approval bypass in OpenClaw before 2026.2.26 allows local users to run approved commands from unintended filesystem locations. For host=node system.run requests, approval preserved the visible cwd string without binding writable parent symlink components to resolved targets. A local user able to retarget a parent symlink between approval and execution can redirect command effects within the command's privileges.
