Doc Text:
A vulnerability was found in the Remoting library in Jenkins core, which handles communication between the Jenkins controller and agents. The ClassLoaderProxy#fetchJar function may allow malicious agents or attackers with Agent/Connect permission to read arbitrary files from the Jenkins controller's file system due to insufficient path restrictions permissions, which could lead to Privilege Escalation and Remote Code Execution (RCE)
