Recommendation: Monitor — no exploitation signal at the moment.

OpenClaw before 2026.5.12 contains a shell option parsing vulnerability that allows combined POSIX shell flags to bypass exec revalidation checks. Attackers can exploit this by using combined shell options to execute inline shell content without intended allowlist validation, potentially enabling unauthorized command execution when the affected feature is enabled.
