CVE-2021-21695 [HIGH] Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins
Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins
The agent-to-controller security subsystem limits which files on the Jenkins controller can be accessed by agent processes.
Multiple vulnerabilities in the file path filtering implementation of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier allow agent processes to read and write arbitrary files on the Jenkins controller file system, and obtain some information about Jenkins controller file systems.
SECURITY-2542 / CVE-2021-21695: `FilePath#listFiles` lists files outside directories with agent read access when following symbolic links.
