Summary

Duplicate Advisory: macOS Swift exec allowlist missed combined POSIX inline flags

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-c226-q6fx-6j6c. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.5.6 contains an allowlist bypass vulnerability in the macOS Swift exec feature that misses combined POSIX inline-command flags. Attackers can execute shell content outside the intended allowlist check by using combined flag forms, potentially allowing unauthorized command execution depending on operator configuration.
