CVE-2022-27204

CSRF vulnerability and missing permission checks in Jenkins Extended Choice Parameter Plugin allow SSRF

Extended Choice Parameter Plugin 346.vd87693c5a_86c and earlier does not perform a permission check on form validation methods. This allows attackers with Overall/Read permission to connect to an attacker-specified URL.

Additionally, these form validation methods do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

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-2022-27204 has a CVSS score of 4.3 (Medium). The vector is network-reachable, low 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 (356.va_90a_94ca_62ec); upgrading removes the vulnerable code path.

1. What is CVE-2022-27204? CVE-2022-27204 is a medium-severity cross-site request forgery (CSRF) vulnerability in org.jenkins-ci.plugins:extended-choice-parameter (maven), affecting versions <= 346.vd87693c5a. It is fixed in 356.va_90a_94ca_62ec. A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones.
2. How severe is CVE-2022-27204? CVE-2022-27204 has a CVSS score of 4.3 (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.
3. Which versions of org.jenkins-ci.plugins:extended-choice-parameter are affected by CVE-2022-27204? org.jenkins-ci.plugins:extended-choice-parameter (maven) versions <= 346.vd87693c5a is affected.
4. Is there a fix for CVE-2022-27204? Yes. CVE-2022-27204 is fixed in 356.va_90a_94ca_62ec. Upgrade to this version or later.
5. Is CVE-2022-27204 exploitable, and should I be worried? Whether CVE-2022-27204 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.

6. What actually determines whether CVE-2022-27204 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.
7. How do I fix CVE-2022-27204? Upgrade org.jenkins-ci.plugins:extended-choice-parameter to 356.va_90a_94ca_62ec or later.
