CSRF Exploit Enables Unauthorized Resumption of Failed Jenkins Multijob Builds

A cross-site request forgery (CSRF) vulnerability in Jenkins Multijob Plugin 662.vd2e0001f6b_b_d and earlier allows attackers to resume failed Multijob builds.

Jenkins Script Security Plugin: Jenkins Script Security Plugin: Information disclosure via missing permission check

A missing permission check in Jenkins Script Security Plugin 1399.ve6a_66547f6e1 and earlier allows attackers with Overall/Read permission to enumerate pending and approved Script Security classpaths.

Jenkins Matrix Authorization Strategy Plugin 2.0-beta-1 through 3.2.9 (both inclusive) invokes parameterless constructors of classes specified in configuration when deserializing inheritance strategies, without restricting the classes that can be instantiated, allowing attackers with Item/Configure permission to instantiate arbitrary types, which may lead to information disclosure or other impacts depending on the classes available on the classpath.

Missing Permission Check Enables Remote URL Connections in Jenkins GitHub Branch Source Plugin

A missing permission check in Jenkins GitHub Branch Source Plugin 1967.vdea_d580c1a_b_a_ and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL with attacker-specified GitHub App credentials.

Stored Cross‑Site Scripting in Jenkins HTML Publisher Plugin

Jenkins HTML Publisher Plugin 427 and earlier does not escape job name and URL in the legacy wrapper file, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

Stored XSS via Improper Job URL Handling in Jenkins GitHub Plugin

Jenkins GitHub Plugin 1.46.0 and earlier improperly processes the current job URL as part of JavaScript implementing validation of the feature "GitHub hook trigger for GITScm polling", resulting in a stored cross-site scripting (XSS) vulnerability exploitable by non-anonymous attackers with Overall/Read permission.

Unrestricted Redirect in Microsoft Entra ID Plugin Enables Phishing Attacks

Jenkins Microsoft Entra ID (previously Azure AD) Plugin 666.v6060de32f87d and earlier does not restrict the redirect URL after login, allowing attackers to perform phishing attacks.

jenkins: Project name disclosure via fingerprints (SECURITY-153)

The Fingerprints pages in Jenkins before 1.638 and LTS before 1.625.2 might allow remote attackers to obtain sensitive job and build name information via a direct request.

org.jenkins-ci.main/jenkins-core: Jenkins: Stored Cross-site Scripting (XSS) via unescaped user-provided offline cause description

Jenkins 2.483 through 2.550 (both inclusive), LTS 2.492.1 through 2.541.1 (both inclusive) does not escape the user-provided description of the "Mark temporarily offline" offline cause, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Agent/Configure or Agent/Disconnect permission.

org.jenkins-ci.main/jenkins-core: Jenkins: Information disclosure via unauthorized access to build parameters

Jenkins 2.550 and earlier, LTS 2.541.1 and earlier accepts Run Parameter values that refer to builds the user submitting the build does not have access to, allowing attackers with Item/Build and Item/Configure permission to obtain information about the existence of jobs, the existence of builds, and if a specified build exists, its display name.

jenkins: Jenkins: Arbitrary file write and potential code execution through crafted archives

Jenkins 2.554 and earlier, LTS 2.541.2 and earlier does not safely handle symbolic links during the extraction of .tar and .tar.gz archives, allowing crafted archives to write files to arbitrary locations on the filesystem, restricted only by file system access permissions of the user running Jenkins. This can be exploited to deploy malicious scripts or plugins on the controller by attackers with Item/Configure permission, or able to control agent processes.

jenkins: Jenkins: Origin validation bypass via DNS rebinding in CLI WebSocket endpoint

Jenkins 2.442 through 2.554 (both inclusive), LTS 2.426.3 through LTS 2.541.2 (both inclusive) performs origin validation of requests made through the CLI WebSocket endpoint by computing the expected origin for comparison using the Host or X-Forwarded-Host HTTP request headers, making it vulnerable to DNS rebinding attacks that allow bypassing origin validation.

Jenkins LoadNinja Plugin 2.1 and earlier stores LoadNinja API keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.

LoadNinja API Keys Unmasked in Jenkins LoadNinja Plugin

Jenkins LoadNinja Plugin 2.1 and earlier does not mask LoadNinja API keys displayed on the job configuration form, increasing the potential for attackers to observe and capture them.

Jenkins SAML Plugin 4.583.vc68232f7018a_ and earlier does not implement a replay cache, allowing attackers able to obtain information about the SAML authentication flow between a user's web browser and Jenkins to replay those requests, authenticating to Jenkins as that user.

Jenkins MCP Server Plugin 0.84.v50ca_24ef83f2 and earlier does not perform permission checks in multiple MCP tools, allowing attackers to trigger builds and obtain information about job and cloud configuration they should not be able to access.
