A vulnerability was found in Jenkins versions weekly before 2.186 and LTS before 2.176.2. Users with Job/Configure permission could specify a relative path escaping the base directory in the file name portion of a file parameter definition. This path would be used to store the uploaded file on the Jenkins master, resulting in an arbitrary file write vulnerability. This vulnerability is the result of an incomplete fix for SECURITY-1074. File parameters that escape the base directory are no longer accepted and the build will fail.
