Jenkins Gogs Plugin provides a webhook endpoint at /gogs-webhook that can be used to trigger builds of jobs. In Gogs Plugin 1.0.15 and earlier, an option to specify a Gogs secret for this webhook is provided, but not enabled by default. This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified job name. Additionally, the output of the webhook endpoint includes whether a job corresponding to the attacker-specified job name exists, even if the attacker has no permission to access it. As of publication of this advisory, there is no fix.
