Summary
Exposure of secrets through system log in Jenkins Structs Plugin
Structs Plugin provides utility functionality used, e.g., in Pipeline to instantiate and configure build steps, typically before their execution.
When Structs Plugin 337.v1b_04ea_4df7c8 and earlier fails to configure a build step, it logs a warning message containing diagnostic information that may contain secrets passed as step parameters.
This can result in accidental exposure of secrets through the default system log.
Structs Plugin 338.v848422169819 inspects the types of actual parameters before logging these warning messages, and limits detailed diagnostic information to FINE level log messages if secrets are involved. These log messages are not displayed in the default Jenkins system log.
Impact
CVE-2024-39458 has a CVSS score of 3.1 (Low). The vector is network-reachable, no privileges required, and user interaction required. 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 (338.v848422169819); 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-2024-39458? CVE-2024-39458 is a low-severity security vulnerability in org.jenkins-ci.plugins:structs (maven), affecting versions < 338.v848422169819. It is fixed in 338.v848422169819.
- How severe is CVE-2024-39458? CVE-2024-39458 has a CVSS score of 3.1 (Low). 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:structs are affected by CVE-2024-39458? org.jenkins-ci.plugins:structs (maven) versions < 338.v848422169819 is affected.
- Is there a fix for CVE-2024-39458? Yes. CVE-2024-39458 is fixed in 338.v848422169819. Upgrade to this version or later.
- Is CVE-2024-39458 exploitable, and should I be worried? Whether CVE-2024-39458 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-2024-39458 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-2024-39458? Upgrade
