AI-suggested
A fixed version is available starting with OpenClaw 2026.4.22. Until upgrading, operators should restart the affected channel runtime after rotating webhook secrets to ensure old secrets are invalidated. Additional mitigations include maintaining narrow channel and tool allowlists, avoiding sharing a Gateway between mutually untrusted users, and disabling the affected webhook feature when not needed.
Description
OpenClaw versions prior to 2026.4.22 have a vulnerability where Slack and Zalo webhook secrets may remain active after a secrets.reload operation. This allows a caller with an old webhook secret to continue sending webhook events during a brief stale-secret window after secret rotation. The vulnerability affects the webhook secret revocation process but does not alter OpenClaw's trusted-operator security model. The impact depends on the operator's configuration and exposure of the affected feature. A fix is available starting with version 2026.4.22.
