An improper authorization vulnerability exists in Jenkins Gerrit Trigger Plugin 2.27.4 and earlier in GerritManagement.java, GerritServer.java, and PluginImpl.java that allows an attacker with Overall/Read access to retrieve some configuration information about Gerrit in Jenkins.

The Gerrit configuration in the Openstack Puppet module for Gerrit (aka puppet-gerrit) improperly marks text/html as a safe mimetype, which might allow remote attackers to conduct cross-site scripting (XSS) attacks via a crafted review.
