Jenkins 2.499 and earlier, LTS 2.492.1 and earlier does not redact encrypted values of secrets when accessing config.xml of views via REST API or CLI. This allows attackers with View/Read permission to view encrypted values of secrets. Jenkins 2.500, LTS 2.492.2 redacts the encrypted values of secrets stored in view config.xml accessed via REST API or CLI for users lacking View/Configure permission.

Jenkins 2.499 and earlier, LTS 2.492.1 and earlier does not redact encrypted values of secrets when accessing config.xml of agents via REST API or CLI.

Jenkins 2.500, LTS 2.492.2 redacts the encrypted values of secrets stored in agent config.xml accessed via REST API or CLI for users lacking Agent/Configure permission.

Various features in Jenkins redirect users to partially user-controlled URLs inside Jenkins. To prevent open redirect vulnerabilities, Jenkins limits redirections to safe URLs (neither absolute nor scheme-relative/network-path reference). In Jenkins 2.499 and earlier, LTS 2.492.1 and earlier, redirects starting with backslash () characters are considered safe. This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site, because …

Jenkins 2.499 and earlier, LTS 2.492.1 and earlier does not require POST requests for the HTTP endpoint toggling collapsed/expanded status of sidepanel widgets (e.g., Build Queue and Build Executor Status widgets), resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to have users toggle their collapsed/expanded status of sidepanel widgets. Additionally, as the API accepts any string as the identifier of the panel ID to be toggled, …

Jenkins provides APIs for fine-grained control of item creation: Authorization strategies can prohibit the creation of items of a given type in a given item group (ACL#hasCreatePermission2). Item types can prohibit creation of new instances in a given item group (TopLevelItemDescriptor#isApplicableIn(ItemGroup)). If an attempt is made to create an item of a prohibited type through the Jenkins CLI or the REST API and either of the above checks fail, Jenkins …

Jenkins Jenkins provides the secretTextarea form field for multi-line secrets. Jenkins 2.478 and earlier, LTS 2.462.2 and earlier does not redact multi-line secret values in error messages generated for form submissions involving the secretTextarea form field. This can result in exposure of multi-line secrets through those error messages, e.g., in the system log. Jenkins 2.479, LTS 2.462.3 redacts multi-line secret values in error messages generated for form submissions involving the …

Jenkins uses the Remoting library (typically agent.jar or remoting.jar) for the communication between controller and agents. This library allows agents to load classes and classloader resources from the controller, so that Java objects sent from the controller (build steps, etc.) can be executed on agents. In addition to individual class and resource files, Remoting also allows Jenkins plugins to transmit entire jar files to agents using the Channel#preloadJar API. As …

Jenkins 2.470 and earlier, LTS 2.452.3 and earlier does not perform a permission check in an HTTP endpoint. This allows attackers with Overall/Read permission to access other users' "My Views". Attackers with global View/Configure and View/Delete permissions are also able to change other users' "My Views". Jenkins 2.471, LTS 2.452.4, LTS 2.462.1 restricts access to a user’s "My Views" to the owning user and administrators.

Jenkins has a built-in command line interface (CLI) to access Jenkins from a script or shell environment. Jenkins uses the args4j library to parse command arguments and options on the Jenkins controller when processing CLI commands. This command parser has a feature that replaces an @ character followed by a file path in an argument with the file’s contents (expandAtFiles). This feature is enabled by default and Jenkins 2.441 and …

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in MetaDataBuilder.checkSize allows for HTTP/2 HPACK header values to exceed their size limit. MetaDataBuilder.java determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication …

Jenkins is vulnerable to a persisted cross-site scripting vulnerability in console notes. Jenkins allows plugins to annotate build logs, adding new content or changing the presentation of existing content while the build is running. Malicious Jenkins users, or users with SCM access, could configure jobs or modify build scripts such that they print serialized console notes that perform cross-site scripting attacks on Jenkins users viewing the build logs.

Jenkins and Jenkins LTS does not properly prevent specifying relative paths that escape a base directory for URLs accessing plugin resource files. This allows users with Overall/Read permission to download files from the Jenkins master they should not have access to.

Users with permission to create or configure agents in Jenkins could configure a launch method called "Launch agent via execution of command on master". This allowed them to run arbitrary shell commands on the master node whenever the agent was supposed to be launched. Configuration of this launch method now requires the Run Scripts permission typically only granted to administrators.

The remote API in Jenkins shows 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.

Jenkins 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 Jenkins users' email addresses if the Mailer Plugin is installed.

The Jenkins 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.

The Jenkins 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.

The Jenkins default form control for passwords and other secrets, <f:password/>, supports form validation. The form validation AJAX requests were sent via GET, which could result in secrets being logged to an HTTP access log in non-default configurations of Jenkins, and made available to users with access to these log files.

Jenkins bundles a version of the commons-fileupload library with a denial-of-service vulnerability.

Jenkins stores metadata related to people, which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping, potentially resulting in problems like overwriting of unrelated configuration files.

Autocompletion suggestions for text fields were not escaped, resulting in a persisted cross-site scripting vulnerability if the source for the suggestions allowed specifying text that includes HTML metacharacters like less-than and greater-than characters.

A race condition during Jenkins 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 race condition during Jenkins 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.

Jenkins allows remote authenticated administrators to conduct XSS attacks via a crafted tool name in a job configuration form, as demonstrated by the JDK tool in Jenkins core.

The re-key admin monitor in Jenkins re-encrypts all secrets in JENKINS_HOME with a new key. It also created a backup directory with all old secrets, and the key used to encrypt them. These backups are world-readable and not removed.
