Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins Nexus Task Runner Plugin version 0.9.2 and earlier has an HTTP endpoint that lacks a permission check. An attacker with Overall/Read permission in Jenkins can make the plugin connect to a URL and use a username and password that the attacker specifies, and the endpoint also accepts non-POST requests, so it is open to cross-site request forgery. No fix is listed.
