Jenkins 2.218 and earlier, LTS 2.204.1 and earlier allowed users with Overall/Read access to view a JVM memory usage chart.

Jenkins GitHub Coverage Reporter Plugin 1.8 and earlier stores secrets unencrypted in its global configuration file on the Jenkins master where they can be viewed by users with access to the master file system or read permissions on the system configuration.

Jenkins Project Inheritance Plugin 19.08.02 and earlier does not redact encrypted secrets in the 'getConfigAsXML' API URL when transmitting job config.xml data to users without Job/Configure.

Jenkins Katalon Plugin 1.0.32 and earlier implements an agent/controller message that does not limit where it can be executed and allows invoking Katalon with configurable arguments, allowing attackers able to control agent processes to invoke Katalon on the Jenkins controller with attacker-controlled version, install location, and arguments, and attackers additionally able to create files on the Jenkins controller (e.g., attackers with Item/Configure permission could archive artifacts) to invoke arbitrary OS commands.

The Jenkins 2.73.1 and earlier, 2.83 and earlier remote API at /queue/item/(ID)/api showed information about tasks in the queue (typically builds waiting to start). This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API endpoint is now only available for tasks that the current user has access to.

Jenkins 2.73.1 and earlier, 2.83 and earlier provides information about Jenkins user accounts which is generally available to anyone with Overall/Read permissions via the /user/(username)/api remote API. This included e.g. Jenkins users' email addresses if the Mailer Plugin is installed. The remote API now no longer includes information beyond the most basic (user ID and name) unless the user requesting it is a Jenkins administrator.

The Jenkins 2.73.1 and earlier, 2.83 and earlier remote API at /job/(job-name)/api contained information about upstream and downstream projects. This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API now only lists upstream and downstream projects that the current user has access to.

The default whitelist included the following unsafe entries: DefaultGroovyMethods.putAt(Object, String, Object); DefaultGroovyMethods.getAt(Object, String). These allowed circumventing many of the access restrictions implemented in the script sandbox by using e.g. currentBuild['rawBuild'] rather than currentBuild.rawBuild. Additionally, the following entries allowed accessing private data that would not be accessible otherwise due to script security: groovy.json.JsonOutput.toJson(Closure); groovy.json.JsonOutput.toJson(Object).

The Config File Provider Plugin is used to centrally manage configuration files that often include secrets, such as passwords. Users with only Overall/Read access to Jenkins were able to access URLs directly that allowed viewing these files. Access to view these files now requires sufficient permissions to configure the provided files, view the configuration of the folder in which the configuration files are defined, or have Job/Configure permissions to a job able to use these files.

The remote API in Jenkins 2.73.1 and earlier, 2.83 and earlier at /computer/(agent-name)/api showed information about tasks (typically builds) currently running on that agent. This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API now only shows information about accessible tasks.

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.

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.

In Jenkins Script Security Plugin version 1.36 and earlier, users with the ability to configure sandboxed Groovy scripts are able to use a type coercion feature in Groovy to create new `File` objects from strings. This allowed reading arbitrary files on the Jenkins master file system. Such a type coercion is now subject to sandbox protection and considered to be a call to the `new File(String)` constructor for the purpose of in-process script approval.

Jenkins Rundeck Plugin 3.6.11 and earlier does not protect access to the /plugin/rundeck/webhook/ endpoint, allowing users with Overall/Read permission to trigger jobs that are configured to be triggerable via Rundeck.

Jenkins Kubernetes Plugin 1.27.3 and earlier allows low-privilege users to access possibly sensitive Jenkins controller environment variables.

A missing permission check in an HTTP endpoint in Jenkins docker-build-step Plugin 2.11 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified TCP or Unix socket URL, and to reconfigure the plugin using the provided connection test parameters, affecting future build step executions.

Jenkins Deployer Framework Plugin 85.v1d1888e8c021 and earlier does not restrict the application path of the applications when configuring a deployment, allowing attackers with Item/Configure permission to upload arbitrary files from the Jenkins controller file system to the selected service.

A missing permission check in Jenkins Mercurial Plugin 2.11 and earlier allows attackers with Overall/Read permission to obtain a list of names of configured Mercurial installations.

Jenkins OpsGenie Plugin 1.9 and earlier transmits API keys in plain text as part of the global Jenkins configuration form and job configuration forms, potentially resulting in their exposure.

Jenkins Build Notifications Plugin 1.5.0 and earlier transmits tokens in plain text as part of the global Jenkins configuration form, potentially resulting in their exposure.

Jenkins Recipe Plugin 1.2 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
