How to Fix CVE-2022-36886

To remediate this vulnerability, upgrade all affected External monitor job 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:external-monitor-job fixed: 192.ve979ca_8b_3ccd 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>external-monitor-job</artifactId>
    <version>192.ve979ca_8b_3ccd</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-2022-36886, 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 External monitor job in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 192.ve979ca_8b_3ccd), 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In External monitor job, 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 External Monitor Job Type Plugin 191.v363d0d1efdf8 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to create runs of an external job. External Monitor Job Type Plugin 192.ve979ca_8b_3ccd requires POST requests for the affected HTTP endpoint.
