Other sources

Jenkins Pipeline: Input Step Plugin 448.v37cea9a10a70 and earlier archives files uploaded for file parameters for Pipeline input steps on the controller as part of build metadata, using the parameter name without sanitization as a relative path inside a build-related directory, allowing attackers able to configure Pipelines to create or replace arbitrary files on the Jenkins controller file system with attacker-specified content.
