Upgrade org.jenkins-ci.main:jenkins-core to version 2.303.3, 2.319 or higher.
Overview
org.jenkins-ci.main:jenkins-core is an open source automation server.
Affected versions of this package are vulnerable to Improper Authorization. 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.
