Summary
Jenkins Code Dx Plugin missing permission checks
Jenkins Code Dx Plugin 3.1.0 and earlier does not perform permission checks in several HTTP endpoints.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL.
Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Code Dx Plugin 4.0.0 requires POST requests and the appropriate permissions for the affected HTTP endpoints.
Impact
CVE-2023-2631 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 (4.0.0); 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-2023-2631? CVE-2023-2631 is a medium-severity security vulnerability in org.jenkins-ci.plugins:codedx (maven), affecting versions < 4.0.0. It is fixed in 4.0.0.
- How severe is CVE-2023-2631? CVE-2023-2631 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.
- Which versions of org.jenkins-ci.plugins:codedx are affected by CVE-2023-2631? org.jenkins-ci.plugins:codedx (maven) versions < 4.0.0 is affected.
- Is there a fix for CVE-2023-2631? Yes. CVE-2023-2631 is fixed in 4.0.0. Upgrade to this version or later.
- Is CVE-2023-2631 exploitable, and should I be worried? Whether CVE-2023-2631 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-2023-2631 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-2023-2631? Upgrade
org.jenkins-ci.plugins:codedxto 4.0.0 or later.
