Summary
Jenkins Folders Plugin information disclosure vulnerability
Jenkins Folders Plugin displays an error message when attempting to access the Scan Organization Folder Log if no logs are available.
In Folders Plugin 6.846.v23698686f0f6 and earlier, this error message includes the absolute path of a log file, exposing information about the Jenkins controller file system.
Folders Plugin 6.848.ve3b_fd7839a_81 does not display the absolute path of a log file in the error message.
Impact
CVE-2023-40338 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 (6.848.ve3b); 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-2023-40338? CVE-2023-40338 is a medium-severity security vulnerability in org.jenkins-ci.plugins:cloudbees-folder (maven), affecting versions < 6.848.ve3b. It is fixed in 6.848.ve3b.
- How severe is CVE-2023-40338? CVE-2023-40338 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:cloudbees-folder are affected by CVE-2023-40338? org.jenkins-ci.plugins:cloudbees-folder (maven) versions < 6.848.ve3b is affected.
- Is there a fix for CVE-2023-40338? Yes. CVE-2023-40338 is fixed in 6.848.ve3b. Upgrade to this version or later.
- Is CVE-2023-40338 exploitable, and should I be worried? Whether CVE-2023-40338 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-2023-40338 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-2023-40338? Upgrade
org.jenkins-ci.plugins:cloudbees-folderto 6.848.ve3b or later.
