The Sidebar Link plugin allows users able to configure jobs, views, and agents to add entries to the sidebar of these objects. There was no input validation, which meant users were able to use javascript: schemes for these links.

GitHub Branch Source provides a list of applicable credential IDs to allow users configuring a job to select the one they'd like to use. This functionality did not check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those could be used as part of an attack to capture the credentials using another vulnerability.

The Periodic Backup Plugin did not perform any permission checks, allowing any user with Overall/Read access to change its settings, trigger backups, restore backups, download backups, and also delete all previous backups via log rotation. Additionally, the plugin was not requiring requests to its API be sent via POST, thereby opening itself to Cross-Site Request Forgery attacks.

jenkins-plugin-subversion: CSRF vulnerability and insufficient permission checks allow capturing credentials (SECURITY-303)

Subversion Plugin connects to a user-specified Subversion repository as part of form validation (e.g. to retrieve a list of tags). This functionality improperly checked permissions, allowing any user with Item/Build permission (but not Item/Configure) to connect to any web server or Subversion server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery attacks.

Parameterized Trigger Plugin fails to check Item/Build permission: The Parameterized Trigger Plugin did not check the build authentication it was running as and allowed triggering any other project in Jenkins.

jenkins: Java deserialization flaw leads to RCE

The remoting module in Jenkins before 2.32 and LTS before 2.19.3 allows remote attackers to execute arbitrary code via a crafted serialized Java object, which triggers an LDAP query to a third-party server.

Tomcat: failure to set httponly flag on cookies

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.

Cross-site scripting (XSS) vulnerability in the Build Failure Analyzer plugin before 1.16.0 in Jenkins allows remote attackers to inject arbitrary web script or HTML via an unspecified parameter.

Directory traversal vulnerability in the Image Gallery plugin before 1.4 in Jenkins allows remote attackers to list arbitrary directories and read arbitrary files via unspecified form fields.

Tomcat: failure to set secure flag on cookies

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.

Directory traversal vulnerability in the TAP plugin before 1.25 in Jenkins allows remote attackers to read arbitrary files via an unspecified parameter.

jenkins: Groovy sandbox protection incomplete in Script Security Plugin (SECURITY-258)

The Script Security plugin before 1.18.1 in Jenkins might allow remote attackers to bypass a Groovy sandbox protection mechanism via a plugin that performs (1) direct field access or (2) get/set array operations.

jenkins: Stored XSS vulnerability in Extra Columns Plugin (SECURITY-136)

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.

jenkins: XSS via a crafted tool name in a job configuration form

Jenkins through 2.93 allows remote authenticated administrators to conduct XSS attacks via a crafted tool name in a job configuration form, as demonstrated by the JDK tool in Jenkins core and the Ant tool in the Ant plugin, aka SECURITY-624.

Jenkins Stack Hammer Plugin 1.0.6 and earlier stores Stack Hammer API keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.

A cross-site request forgery (CSRF) vulnerability in Jenkins Simple Queue Plugin 1.4.6 and earlier allows attackers to change and reset the build queue order.

Jenkins Cadence vManager Plugin 4.0.0-282.v5096a_c2db_275 and earlier stores Verisium Manager vAPI keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.

Jenkins monitor-remote-job Plugin 1.0 stores passwords unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.

Jenkins AsakusaSatellite Plugin 0.1.1 and earlier stores AsakusaSatellite API keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.

Jenkins AsakusaSatellite Plugin 0.1.1 and earlier does not mask AsakusaSatellite API keys displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
