Stored XSS in Jenkins Git Parameter Plugin 0.9.11 and earlier allows remote authenticated users to run script in another user's browser. The GitParameterDefinition index.jelly view places the attacker-controlled parameter name into an entry title without HTML escaping. Job/Configure permission is required, and execution occurs when another user views the parameter UI, enabling access or actions within that user's Jenkins session.
