Recommendation: Monitor — no exploitation signal at the moment.

OpenClaw before 2026.4.24 contains a token revocation vulnerability allowing callers with revoked slash tokens to continue executing commands during monitor refresh windows. Attackers can exploit stale token acceptance to invoke slash command behavior briefly after token revocation, potentially executing unauthorized actions depending on operator configuration.
