An insufficiently protected credentials vulnerability exists in Jenkins Repository Connector Plugin 1.2.4 and earlier in src/main/java/org/jvnet/hudson/plugins/repositoryconnector/ArtifactDeployer.java, src/main/java/org/jvnet/hudson/plugins/repositoryconnector/Repository.java, src/main/java/org/jvnet/hudson/plugins/repositoryconnector/UserPwd.java that allows an attacker with local file system access or control of a Jenkins administrator's web browser (e.g. malicious extension) to retrieve the password stored in the plugin configuration.

A flaw was found in the Jenkins plugin. Affected versions of the Jenkins Mercurial Plugin allow attackers who can configure pipelines to check out some SCM repositories stored on the Jenkins controller's file system. This is accomplished by using local paths as SCM URLs, obtaining limited information about other projects' SCM contents.

Jenkins Git Plugin 4.11.1 and earlier allows attackers able to configure pipelines to check out some SCM repositories stored on the Jenkins controller's file system using local paths as SCM URLs, obtaining limited information about other projects' SCM contents.
