OpenClaw versions prior to 2026.2.25 contain a time-of-check-time-of-use vulnerability in approval-bound system.run execution where the cwd parameter is validated at approval time but resolved at execution time. Attackers can retarget a symlinked cwd between approval and execution to bypass command execution restrictions and execute arbitrary commands on node hosts.
