Jenkins GitHub Branch Source Plugin 1967.1969.v205fd594c821 and earlier does not perform a permission check in an HTTP endpoint that lists the GitHub API endpoints configured in the global plugin configuration. This allows attackers with Overall/Read permission to obtain the URLs of GitHub Enterprise servers configured by administrators. This vulnerability has been reported through the Jenkins Bug Bounty Program sponsored by the European Commission. GitHub Branch Source Plugin 1967.1970.vd86979736546 requires Overall/Manage …

Jenkins GitHub Branch Source Plugin versions 1967.vdea_d580c1a_b_a_ and earlier do not perform a permission check in a method implementing form validation. This allows attackers with Overall/Read permission to connect to an attacker-specified URL with attacker-specified GitHub App credentials. GitHub Branch Source Plugin 1967.1969.v205fd594c821 requires Overall/Manage permission to perform the connection test.

A server-side request forgery vulnerability exists in Jenkins GitHub Branch Source Plugin that allows attackers with Overall/Read access to cause Jenkins to send a GET request to a specified URL.

GitHub Branch Source provides a list of applicable credential IDs to allow users configuring a job to select the one they'd like to use. This functionality did not check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those could be used as part of an attack to capture the credentials using another vulnerability.

GitHub Branch Source Plugin connects to a user-specified GitHub API URL as part of form validation and completion. This functionality improperly checked permissions, allowing any user with Overall/Read access to Jenkins to connect to any web server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins …
