A man in the middle vulnerability exists in Jenkins vSphere Plugin 2.16 and older in VSphere.java that disables SSL/TLS certificate validation by default.

Jenkins Maven Release Plugin 0.16.1 and earlier does not configure the XML parser to prevent XML external entity (XXE) attacks, allowing man-in-the-middle attackers to have Jenkins parse crafted XML documents.

Role-based Authorization Strategy Plugin was not requiring requests to its API be sent via POST, thereby opening itself to Cross-Site Request Forgery attacks. This allowed attackers to add administrator role to any user, or to remove the authorization configuration, preventing legitimate access to Jenkins.

A cross-site request forgery vulnerability in Jenkins Build Failure Analyzer Plugin 1.24.1 and earlier allows attackers to have Jenkins evaluate a computationally expensive regular expression.

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an issue in the Jenkins user database authentication realm: create an account if signup is enabled; or create an account if the victim is an administrator, possibly deleting the existing default admin user in the process and allowing a wide variety of impacts.

Poll SCM Plugin was not requiring requests to its API be sent via POST, thereby opening itself to Cross-Site Request Forgery attacks. This allowed attackers to initiate polling of projects with a known name. While Jenkins in general does not consider polling to be a protection-worthy action as it's similar to cache invalidation, the plugin specifically adds a permission to be able to use this functionality, and this issue undermines that permission.

Jenkins Favorite Plugin version 2.2.0 and older is vulnerable to CSRF resulting in data modification

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.

A cross-site request forgery vulnerability in Jenkins Ansible Tower Plugin 0.9.1 and earlier in the TowerInstallation.TowerInstallationDescriptor#doTestTowerConnection form validation method allowed attackers permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins

A race condition during Jenkins 2.94 and earlier; 2.89.1 and earlier startup could result in the wrong order of execution of commands during initialization. There is a very short window of time after startup during which Jenkins may no longer show the 'Please wait while Jenkins is getting ready to work' message but Cross-Site Request Forgery (CSRF) protection may not yet be effective.

A cross-site request forgery vulnerability exists in Jenkins Warnings Next Generation Plugin 2.1.1 and earlier in src/main/java/io/jenkins/plugins/analysis/warnings/groovy/GroovyParser.java that allows attackers to execute arbitrary code via a form validation HTTP endpoint.

Users who cached their CLI authentication before Jenkins was updated to 2.150.2 and newer, or 2.160 and newer, would remain authenticated in Jenkins 2.171 and earlier and Jenkins LTS 2.164.1 and earlier, because the fix for CVE-2019-1003004 in these releases did not reject existing remoting-based CLI authentication caches.

A race condition during Jenkins 2.81 through 2.94 (inclusive); 2.89.1 startup could result in the wrong order of execution of commands during initialization. This could in rare cases result in failure to initialize the setup wizard on the first startup. This resulted in multiple security-related settings not being set to their usual strict default.
