Lack of authentication mechanism in Jenkins DotCi Plugin webhook

DotCi Plugin provides a webhook endpoint at /githook/ that can be used to trigger builds of the job for a GitHub repository.

In DotCi Plugin 2.40.00 and earlier, this endpoint can be accessed without authentication.

This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified repository for attacker-specified commits.

This plugin has been suspended.
