Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Jenkins Contrast Continuous Application Security Plugin, versions before 3.12, has a missing permission check and a cross-site request forgery flaw in an HTTP endpoint that tests the connection to a Contrast TeamServer. An attacker with Overall/Read permission can make the server connect to an attacker-specified URL using supplied credentials, and a cross-site request forgery attack can trigger the same request. Upgrade to version 3.12 or later, which requires Overall/Administer permission and POST requests for this endpoint.
