Jenkins before 1.638 and LTS before 1.625.2 do not properly restrict access to API tokens which might allow remote administrators to gain privileges and run scripts by using an API token of another user.

In Jenkins Templating Engine Plugin 2.5.3 and earlier, libraries defined in folders are not subject to sandbox protection, allowing attackers with Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM.

The combination filter Groovy script in Jenkins before 1.600 and LTS before 1.596.1 allows remote authenticated users with job configuration permission to gain privileges and execute arbitrary code on the master via unspecified vectors.

Jenkins FindBugs Plugin 4.71 and earlier processes XML external entities in files it parses as part of the build process, allowing attackers with user permissions in Jenkins to extract secrets from the Jenkins master, perform server-side request forgery, or denial-of-service attacks.

Jenkins Pipeline: Supporting APIs Plugin 2.17 and earlier have an arbitrary code execution due to incomplete sandbox protection: Methods related to Java deserialization like readResolve implemented in Pipeline scripts were not subject to sandbox protection, and could therefore execute arbitrary code. This could be exploited e.g. by regular Jenkins users with the permission to configure Pipelines in Jenkins, or by trusted committers to repositories containing Jenkinsfiles.

Jenkins Checkstyle Plugin 3.49 and earlier processes XML external entities in files it parses as part of the build process, allowing attackers with user permissions in Jenkins to extract secrets from the Jenkins master, perform server-side request forgery, or denial-of-service attacks.

An improper authorization vulnerability exists in Jenkins vSphere Plugin 2.16 and older in Clone.java, CloudSelectorParameter.java, ConvertToTemplate.java, ConvertToVm.java, Delete.java, DeleteSnapshot.java, Deploy.java, ExposeGuestInfo.java, FolderVSphereCloudProperty.java, PowerOff.java, PowerOn.java, Reconfigure.java, Rename.java, RenameSnapshot.java, RevertToSnapshot.java, SuspendVm.java, TakeSnapshot.java, VSphereBuildStepContainer.java, vSphereCloudProvisionedSlave.java, vSphereCloudSlave.java, vSphereCloudSlaveTemplate.java, VSphereConnectionConfig.java, vSphereStep.java that allows attackers to perform form validation related actions, including sending numerous requests to the configured vSphere server, potentially resulting in denial of service, or send credentials stored in Jenkins with known ID to an attacker-specified server ("test connection").

An improper authorization vulnerability exists in Jenkins Jira Plugin 3.0.1 and earlier in JiraSite.java that allows attackers with Overall/Read access to have Jenkins connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Jenkins OpenId Connect Authentication Plugin 4.452.v2849b_d3945fa_ and earlier, except 4.438.440.v3f5f201de5dc, treats usernames as case-insensitive, allowing attackers on Jenkins instances configured with a case-sensitive OpenID Connect provider to log in as any user by providing a username that differs only in letter case, potentially gaining administrator access to Jenkins.

Jenkins DRY Plugin 2.49 and earlier processes XML external entities in files it parses as part of the build process, allowing attackers with user permissions in Jenkins to extract secrets from the Jenkins master, perform server-side request forgery, or denial-of-service attacks.

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to a login command which allowed impersonating any Jenkins user. The `login` command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance.

Directory traversal vulnerability in the CLI job creation (hudson/cli/CreateJobCommand.java) in Jenkins before 1.551 and LTS before 1.532.2 allows remote authenticated users to overwrite arbitrary files via the job name.

BuildTrigger in Jenkins before 1.551 and LTS before 1.532.2 allows remote authenticated users to bypass access restrictions and execute arbitrary jobs by configuring a job to trigger another job. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7330.

Jenkins before 1.551 and LTS before 1.532.2 does not invalidate the API token when a user is deleted, which allows remote authenticated users to retain access via the token.

Jenkins WMI Windows Agents Plugin 1.8 and earlier includes the Windows Remote Command library which has a buffer overflow vulnerability that may allow users able to connect to a named pipe to execute commands on the Windows agent machine.

Jenkins main before 1.482 and LTS before 1.466.2 allows remote attackers with read access and HTTP access to Jenkins master to insert data and execute arbitrary code.

Jenkins Literate Plugin 1.0 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerability.

Jenkins OpenShift Pipeline Plugin 1.0.56 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerability.

Jenkins CryptoMove Plugin 0.1.33 and earlier allows attackers with Job/Configure access to execute arbitrary OS commands on the Jenkins master as the OS user account running Jenkins.

Jenkins Sounds Plugin 0.5 and earlier does not perform permission checks in URLs performing form validation, allowing attackers with Overall/Read access to execute arbitrary OS commands as the OS user account running Jenkins.

Jenkins Gitlab Authentication Plugin 1.5 and earlier does not perform group authorization checks properly, resulting in a privilege escalation vulnerability.

Jenkins SCM Filter Jervis Plugin 0.2.1 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerability.

Jenkins Google Kubernetes Engine Plugin 0.8.0 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerability.

Jenkins Play Framework Plugin 1.0.2 and earlier lets users specify the path to the `play` command on the Jenkins master for a form validation endpoint, resulting in an OS command injection vulnerability exploitable by users able to store such a file on the Jenkins master.

Jenkins Shared Library Version Override Plugin 17.v786074c9fce7 and earlier declares folder-scoped library overrides as trusted, so that they're not executed in the Script Security sandbox, allowing attackers with Item/Configure permission on a folder to configure a folder-scoped library override that runs without sandbox protection.

Jenkins Speaks! Plugin, all current versions, allows users with Job/Configure permission to run arbitrary Groovy code inside the Jenkins JVM, effectively elevating privileges to Overall/Run Scripts.

A sandbox bypass vulnerability exists in Jenkins Email Extension Plugin 2.64 and earlier in pom.xml, src/main/java/hudson/plugins/emailext/ExtendedEmailPublisher.java, src/main/java/hudson/plugins/emailext/plugins/content/EmailExtScript.java, src/main/java/hudson/plugins/emailext/plugins/content/ScriptContent.java, src/main/java/hudson/plugins/emailext/plugins/trigger/AbstractScriptTrigger.java that allows attackers with Job/Configure permission to execute arbitrary code on the Jenkins master JVM.
