Summary Duplicate Advisory: OpenClaw's POSIX node system.run safe-bin allowlist could be widened by shell expansion ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-mhq8-78pj-5j79. This link is maintained to preserve external references. ### Original Description 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.
