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.

GitHub Branch Source Plugin connects to a user-specified GitHub API URL (e.g. GitHub Enterprise) as part of form validation and completion (e.g. to verify Scan Credentials are correct). This functionality improperly checked permissions, allowing any user with Overall/Read access to Jenkins to connect to any web 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.

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.

A cross-site request forgery vulnerability in Jenkins RapidDeploy Plugin 4.1 and earlier allows attackers to connect to an attacker-specified web server.

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 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.

A cross-site request forgery vulnerability in Jenkins Team Concert Plugin 1.3.0 and earlier allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

A cross-site request forgery vulnerability in Jenkins Google Compute Engine Plugin 4.1.1 and earlier in ComputeEngineCloud#doProvision could be used to provision new agents.

A cross-site request forgery vulnerability in Jenkins Alauda Kubernetes Suport Plugin 2.3.0 and earlier allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing the Kubernetes service account token or credentials stored in Jenkins.

A cross-site request forgery vulnerability in Jenkins WebSphere Deployer Plugin 1.6.1 and earlier allows attackers to perform connection tests and determine whether files with an attacker-specified path exist on the Jenkins master file system.

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.

A cross-site request forgery vulnerability in Jenkins XL TestView Plugin 1.2.0 and earlier in XLTestView.XLTestDescriptor#doTestConnection allows users with Overall/Read access to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Jenkins before 1.640 and LTS before 1.625.2 allow remote attackers to bypass the CSRF protection mechanism via unspecified vectors.

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.

A cross-site request forgery vulnerability in Jenkins JClouds Plugin 2.14 and earlier in BlobStoreProfile.DescriptorImpl#doTestConnection and JCloudsCloud.DescriptorImpl#doTestConnection allowed users with Overall/Read access to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

A cross-site request forgery vulnerability in Jenkins CRX Content Package Deployer Plugin 1.8.1 and earlier allowed attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

A cross-site request forgery vulnerability in Jenkins Deploy WebLogic Plugin allows attackers to connect to an attacker-specified URL using attacker-specified credentials, or determine whether a file or directory with an attacker-specified path exists on the Jenkins master file system.

Jenkins 2.191 and earlier, LTS 2.176.2 and earlier allowed users to obtain CSRF tokens without an associated web session ID, resulting in CSRF tokens that did not expire and could be used to bypass CSRF protection for the anonymous user.

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 cross-site request forgery vulnerability in Jenkins ElasticBox Jenkins Kubernetes CI/CD Plugin allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

A cross-site request forgery vulnerability in Jenkins Maven Release Plugin 0.14.0 and earlier in the M2ReleaseAction#doSubmit method allowed attackers to perform releases with attacker-specified options.

Jenkins GitHub Authentication Plugin 0.31 and earlier did not use the state parameter of OAuth to prevent CSRF.

A cross-site request forgery vulnerability in Jenkins Dynatrace Application Monitoring Plugin 2.1.3 and earlier allowed attackers to connect to an attacker-specified URL using attacker-specified credentials.

A cross-site request forgery vulnerability exists in Jenkins Warnings Plugin 5.0.0 and earlier in src/main/java/hudson/plugins/warnings/GroovyParser.java that allows attackers to execute arbitrary code via a form validation HTTP endpoint.

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.

Cross-site request forgery (CSRF) vulnerability in Jenkins before 1.640 and LTS before 1.625.2 allows remote attackers to hijack the authentication of administrators for requests that have unspecified impact via vectors related to the HTTP GET method.

Jenkins before 1.638 and LTS before 1.625.2 uses a publicly accessible salt to generate CSRF protection tokens, which makes it easier for remote attackers to bypass the CSRF protection mechanism via a brute force attack.

A cross-site request forgery (CSRF) vulnerability in Jenkins EasyQA Plugin 1.0 and earlier allows attackers to connect to an attacker-specified HTTP server.
