Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins NUnit Plugin versions before 0.28 (Maven org.jenkins-ci.plugins:nunit) have a flaw in an agent-to-controller message that parses files in a user-specified directory as test results. An attacker who controls agent processes can read test results from files in an attacker-specified directory on the Jenkins controller. Upgrade to version 0.28 or later, which changes the message so it runs on the controller side rather than being sent from agents.
