Overview
org.jenkins-ci.main:jenkins-core is an open source automation server.
Affected versions of this package are vulnerable to Improper Access Control. An incorrect access restriction vulnerability was found in Jenkins. The directories agents are allowed to access include the directories that store build-related information, intended to allow agents to store build-related metadata during build execution. As a consequence, this allows an attacker who controls agent process to read and write the contents of any build directory stored in Jenkins with very few restrictions (build.xml and some Pipeline-related metadata).
