Description

Jenkins Pipeline: Input Step Plugin 448.v37cea_9a_10a_70 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.
