AI-suggested
A fix is available in OpenClaw version 2026.4.24. Until systems are updated, operators should restart or refresh the Mattermost monitor after token rotation to ensure revoked tokens are no longer accepted. Additionally, it is recommended to keep channel and tool allowlists narrow, avoid sharing a Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
Description
OpenClaw versions prior to 2026.4.24 have a vulnerability where Mattermost slash token revocation may not take immediate effect, allowing a revoked token to be accepted until the monitor refreshes. This issue affects the slash command feature when enabled and reachable. The vulnerability does not affect the overall trusted-operator model of OpenClaw. The practical impact depends on configuration and exposure to lower-trust inputs. A fix is available starting with version 2026.4.24. Until patched, restarting or refreshing the Mattermost monitor after token rotation mitigates the issue. Additional hardening includes restricting channel and tool allowlists, avoiding shared Gateways among untrusted users, and disabling the feature if not needed.
