Jenkins Git Parameter Plugin 462.vdcf3df2ed2ca_ and earlier does not perform a permission check in an HTTP endpoint that populates the list of values for Git parameters by querying the SCM configured on a job, using the SCM credentials configured in Jenkins. This allows attackers with Item/Read permission to obtain information about the SCM repository used by a job they would otherwise be unable to access, such as branch names, tag names, and revision metadata. Git Parameter Plugin 462.463.v496a_59f698e5 requires Item/Build permission to populate the list of values for Git parameters.
