Jenkins Relution Enterprise Appstore Publisher Plugin stores credentials unencrypted in its global configuration file on the Jenkins master where they can be viewed by users with access to the master file system.

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.

Jenkins Simple Travis Pipeline Runner Plugin 1.0 and earlier specifies unsafe values in its custom Script Security whitelist, allowing attackers able to execute Script Security protected scripts to execute arbitrary code.

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.

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 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.

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 Job Configuration History Plugin 1227.v7a_79fc4dc01f and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

Jenkins SSH2 Easy Plugin 1.4 and earlier does not verify that permissions configured to be granted are enabled, potentially allowing users formerly granted (typically optional permissions, like Overall/Manage) to access functionality they're no longer entitled to.

Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates a temporary file in the system temporary directory with the default permissions for newly created files when installing a plugin from a URL, potentially allowing attackers with access to the system temporary directory to replace the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.

Jenkins Pipeline: Groovy Plugin 2648.va9433432b33c and earlier uses the same checkout directories for distinct SCMs when reading the script file (typically Jenkinsfile) for Pipelines, allowing attackers with Item/Configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.

Jenkins before versions 2.44, 2.32.2 is vulnerable to a remote code execution vulnerability involving the deserialization of various types in javax.imageio in XStream-based APIs (SECURITY-383).

Jenkins File Parameter Plugin 285.v757c5b_67a_c25 and earlier does not restrict the name (and resulting uploaded file name) of Stashed File Parameters, allowing attackers with Item/Configure permission to create or replace arbitrary files on the Jenkins controller file system with attacker-specified content.

Missing permission checks in Jenkins SAML Single Sign On(SSO) Plugin 2.0.2 and earlier allow attackers with Overall/Read permission to send an HTTP request to an attacker-specified URL and parse the response as XML, or parse a local file on the Jenkins controller as XML.

Jenkins iceScrum Plugin 1.1.6 and earlier does not sanitize iceScrum project URLs on build views, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure jobs.

An arbitrary file write vulnerability in Jenkins Pipeline Utility Steps Plugin 2.15.2 and earlier allows attackers able to provide crafted archives as parameters to create or replace arbitrary files on the agent file system with attacker-specified content.

Arbitrary code execution due to incomplete sandbox protection: Constructors, instance variable initializers, and instance initializers 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 JUnit Plugin 1.23 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 CCM Plugin 3.1 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 PMD 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.

Jenkins RapidDeploy Plugin 4.2 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

Jenkins 2.470 and earlier, LTS 2.452.3 and earlier allows agent processes to read arbitrary files from the Jenkins controller file system by using the `ClassLoaderProxy#fetchJar` method in the Remoting library.
