Summary
Users with Overall/Read access can enumerate credential IDs in Pipeline GitHub Notify Step Plugin
Pipeline GitHub Notify Step Plugin 1.0.4 and earlier provides a list of applicable credential IDs to allow users configuring the plugin to select the one to use.
This functionality does not correctly check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those can be used as part of an attack to capture the credentials using another vulnerability.
An enumeration of credentials IDs in Pipeline GitHub Notify Step Plugin 1.0.5 requires the permission to configure a project.
Impact
CVE-2020-2118 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 (1.0.5); 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-2020-2118? CVE-2020-2118 is a medium-severity security vulnerability in org.jenkins-ci.plugins:pipeline-build-step (maven), affecting versions < 1.0.5. It is fixed in 1.0.5.
- How severe is CVE-2020-2118? CVE-2020-2118 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:pipeline-build-step are affected by CVE-2020-2118? org.jenkins-ci.plugins:pipeline-build-step (maven) versions < 1.0.5 is affected.
- Is there a fix for CVE-2020-2118? Yes. CVE-2020-2118 is fixed in 1.0.5. Upgrade to this version or later.
- Is CVE-2020-2118 exploitable, and should I be worried? Whether CVE-2020-2118 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-2020-2118 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-2020-2118? Upgrade
org.jenkins-ci.plugins:pipeline-build-stepto 1.0.5 or later.
