Description
Jenkins before version 2.319 does not limit agent read/write access to the libs/ directory inside build directories when using the FilePath APIs. This directory is used by the "Pipeline: Shared Groovy Libraries" Plugin to store copies of shared libraries.
This allows attackers in control of agent processes to replace the code of a trusted library with a modified variant, resulting in unsandboxed code execution in the Jenkins controller process.
Jenkins 2.319 prohibits agent read/write access to the libs/ directory inside build directories.
