DescriptionCVE.org

OpenClaw before 2026.4.22 contains an authentication bypass vulnerability in the Control UI bootstrap config endpoint that allows unauthenticated attackers to read sensitive configuration fields. Attackers can access the bootstrap config route without a valid Gateway token to expose sensitive bootstrap and config information intended only for authenticated Control UI sessions.

AnalysisAI

Authentication bypass in OpenClaw before version 2026.4.22 allows unauthenticated attackers to read sensitive bootstrap and configuration metadata from the Control UI config endpoint when Gateway authentication is enabled. The vulnerability exposes internal bootstrap information and configuration fields intended only for authenticated Control UI sessions via an unprotected HTTP GET request to the /__openclaw/control-ui-config.json endpoint, with no user interaction required.

Technical ContextAI

OpenClaw is a Node.js/npm-based gateway and control UI application that implements optional Gateway authentication via token-based access control. The vulnerability exists in the HTTP request handler for the Control UI bootstrap config endpoint (/__openclaw/control-ui-config.json). When Gateway authentication is enabled via gateway.auth configuration, the bootstrap config route was not enforcing the same authentication checks applied to other authenticated Control UI reads. The CWE-862 (Missing Authorization) root cause indicates the application failed to verify the requester's authentication credentials before serving sensitive bootstrap metadata. The fix adds asynchronous authentication validation to the bootstrap config handler, ensuring all requests pass through the Gateway read-auth verification path before returning configuration JSON.

RemediationAI

Upgrade OpenClaw to version 2026.4.22 or later immediately. The vendor has released patched version 2026.4.22 (commit 2321d67263bc710e357644d59f746b08d891051b) with authentication enforcement on the bootstrap config endpoint. Update via npm: npm install openclaw@2026.4.22 or higher, then restart the application. No workarounds are available for versions prior to 2026.4.22 if Gateway authentication is enabled; however, temporarily disabling Gateway authentication (gateway.auth: false) will mitigate the exposure until upgrade is possible, though this removes authentication protection from all Control UI reads and is not recommended for production. Verify the fix by confirming that unauthenticated GET requests to /__openclaw/control-ui-config.json receive a 401 Unauthorized response when Gateway authentication is enabled.
