Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
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.
