Technical Analysis
The openclaw CLI's Google Chat app-url webhook verification mechanism accepted add-on principals that were not bound to the intended deployment, allowing unauthorized principals to be accepted. The issue was addressed by requiring exact matching of expected add-on principals and rejecting unexpected issuers in the authentication code. The fix was shipped in version 2026.3.22 and later versions.
Potential Impact
Improper authentication acceptance could allow unauthorized principals to interact with the webhook, potentially leading to integrity violations. Confidentiality and availability impacts are low or none. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade openclaw CLI to version 2026.3.22 or later where the fix is implemented. The fix enforces strict principal matching in webhook authentication, preventing acceptance of unintended add-on principals.
