Summary
Lack of authentication mechanism in Jenkins Git Plugin webhook
Full technical description
Git Plugin provides a webhook endpoint at /git/notifyCommit that can be used to notify Jenkins of changes to an SCM repository. For its most basic functionality, this endpoint receives a repository URL, and Jenkins will schedule polling for all jobs configured with the specified repository. In Git Plugin 4.11.3 and earlier, this endpoint can be accessed with GET requests and without authentication.
This webhook endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Git Plugin 4.11.4 requires a token parameter which will act as an authentication for the webhook endpoint. While GET requests remain allowed, attackers would need to be able to provide a webhook token. For more information see the plugin documentation.
Impact
A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones. Typical impact: state-changing actions performed as the victim without their consent.
CVE-2022-36882 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.11.4); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2022-36882? CVE-2022-36882 is a medium-severity cross-site request forgery (CSRF) vulnerability in org.jenkins-ci.plugins:git (maven), affecting versions <= 4.11.3. It is fixed in 4.11.4. A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones.
- How severe is CVE-2022-36882? CVE-2022-36882 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of org.jenkins-ci.plugins:git are affected by CVE-2022-36882? org.jenkins-ci.plugins:git (maven) versions <= 4.11.3 is affected.
- Is there a fix for CVE-2022-36882? Yes. CVE-2022-36882 is fixed in 4.11.4. Upgrade to this version or later.
- Is CVE-2022-36882 exploitable, and should I be worried? Whether CVE-2022-36882 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2022-36882 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2022-36882? Upgrade
org.jenkins-ci.plugins:gitto 4.11.4 or later.
