Agent-to-controller security bypass in Jenkins Semantic Versioning Plugin

Published January 26, 2023Updated November 8, 2023Source: osv

Summary

Jenkins Semantic Versioning Plugin 1.14 and earlier does not restrict execution of an controller/agent message to agents, and implements no limitations about the file path that can be parsed, allowing attackers able to control agent processes to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
