CVE-2026-53824 Details
Description
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.
A token revocation vulnerability has been identified in OpenClaw versions prior to 2026.4.24. This vulnerability allows callers with revoked Mattermost slash tokens to continue executing commands during periods when the monitor has not yet refreshed. Attackers can take advantage of this delay in token revocation to briefly invoke slash command behaviors after a token has been revoked, potentially leading to unauthorized actions depending on the operator's configuration.
Users can refresh the Mattermost monitor after rotating tokens to clear any stale token acceptance. In general, it is advisable to keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
