| Doc Text: |
A flaw was found in Jenkins Remoting. This vulnerability allows agent processes, code running on agents, and attackers with Agent/Connect permission to bypass the JEP-200 deserialization filter. This bypass occurs because the filter is not applied to classes resolved through a fallback path in the Remoting deserialization implementation. Successful exploitation could lead to arbitrary code execution on the Jenkins controller.
