Jenkins before 1.586 does not set the HttpOnly flag in a Set-Cookie header for session cookies when run on Tomcat 7.0.41 or later, which makes it easier for remote attackers to obtain potentially sensitive information via script access to cookies.Show less

Jenkins before 1.586 does not set the secure flag on session cookies when run on Tomcat 7.0.41 or later, which makes it easier for remote attackers to capture cookies by intercepting their transmission within an HTTP session.Show less

The re-key admin monitor was introduced in Jenkins 1.498 and re-encrypted all secrets in JENKINS_HOME with a new key. It also created a backup directory with all old secrets, and the key used to encrypt them. These backups were world-readable and not removed afterwards. Jenkins now deletes the backup directory, if present. Upgrading from before 1.498 will no longer create a backup directory. Administrators relying on file access permissions in their manually created backups are advised to check them for the directory $JENKINS_HOME/jenkins.security.RekeySecretAdminMonitor/backups, and delete it if present.Show less

Cross-site scripting (XSS) vulnerability in the Extra Columns plugin before 1.17 in Jenkins allows remote attackers to inject arbitrary web script or HTML by leveraging failure to filter tool tips through the configured markup formatter.Show less

The API URL computer/(master)/api/xml in Jenkins before 2.3 and LTS before 1.651.2 allows remote authenticated users with extended read permission for the master node to obtain sensitive information about the global configuration via unspecified vectors.Show less

Multiple open redirect vulnerabilities in Jenkins before 2.3 and LTS before 1.651.2 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors related to "scheme-relative" URLs.Show less

Jenkins before 2.3 and LTS before 1.651.2 allows remote authenticated users to trigger updating of update site metadata by leveraging a missing permissions check. NOTE: this issue can be combined with DNS cache poisoning to cause a denial of service (service disruption).Show less

Jenkins before 2.3 and LTS before 1.651.2 allow remote authenticated users with read access to obtain sensitive plugin installation information by leveraging missing permissions checks in unspecified XML/JSON API endpoints.Show less

CRLF injection vulnerability in the CLI command documentation in Jenkins before 1.650 and LTS before 1.642.2 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.Show less
