jenkins: FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions
FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
An incorrect permissions validation vulnerability was found in Jenkins. The FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions, which may allow an attacker who has access to any of these operations to be able to read and write arbitrary files on the Jenkins controller file system.
Mitigation: Red Hat has investigated whether a possible mitigation exists for this issue, a

CVE-2021-21694 [CRITICAL] 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-2541 / CVE-2021-21694: `FilePath#toURI`, `FilePath#hasSymlink`, `FilePath#absolutize`, `FilePath#isDescendant`, and `FilePath#get*DiskSpace` do not check any permissions.
