How to Fix CVE-2026-42525

To remediate this vulnerability, upgrade all affected Azure ad dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.jenkins-ci.plugins:azure-ad fixed: 667.v4c5827a 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>azure-ad</artifactId>
    <version>667.v4c5827a</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-42525, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

Analyze the terminal output to locate any version of Azure ad in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 667.v4c5827a), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Azure ad, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Jenkins Microsoft Entra ID (previously Azure AD) Plugin versions 666.v6060de32f87d and earlier do not restrict the redirect URL after login. This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication. Microsoft Entra ID (previously Azure AD) Plugin 667.v4c5827a_e74a_0 only redirects to relative (Jenkins) URLs.
