OpenClaw before 2026.5.18 contains a policy enforcement vulnerability in system.run safe-bin allowlist validation that allows shell expansion to modify command interpretation on POSIX nodes. Authenticated operators can exploit shell metacharacters in approved commands to read unintended node-local files and expose sensitive configuration data.
