Jenkins GitHub Plugin 1.34.4 and earlier uses a non-constant time comparison function when checking whether the provided and computed webhook signatures are equal, allowing attackers to use statistical methods to obtain a valid webhook signature.

Security readout for executives and security teams

Jenkins GitHub Plugin 1.34.4 and earlier compared webhook signatures in a way that could leak timing information. An attacker with network access to the webhook endpoint could statistically infer a valid signature, weakening trust in GitHub webhook requests. Exposure is likely limited to Jenkins instances using Jenkins GitHub Plugin 1.34.4 or earlier with reachable GitHub webhook processing. Treat as a targeted CI/CD trust issue, not a confirmed mass-exploitation event. Prioritize affected internet-reachable Jenkins environments and systems where GitHub webhooks can trigger sensitive automation. Mitigation focus: Identify Jenkins instances using Jenkins GitHub Plugin 1.34.4 or earlier.; Check the Jenkins advisory and plugin update center for the fixed version.; Upgrade the plugin according to Jenkins vendor guidance..
