Summary
Missing permission checks in Jenkins XebiaLabs XL Release Plugin allow enumerating credentials IDs
XebiaLabs XL Release Plugin 22.0.0 and earlier does not perform permission checks in several HTTP endpoints.
This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.
An enumeration of credentials IDs in XebiaLabs XL Release Plugin 22.0.1 requires Overall/Administer permission.
Impact
The application does not perform an authorization check before performing a sensitive operation. Typical impact: unauthorized access to restricted functionality or data.
CVE-2022-34779 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 (22.0.1); 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-2022-34779? CVE-2022-34779 is a medium-severity missing authorization vulnerability in com.xebialabs.ci:xlrelease-plugin (maven), affecting versions <= 22.0.0. It is fixed in 22.0.1. The application does not perform an authorization check before performing a sensitive operation.
- How severe is CVE-2022-34779? CVE-2022-34779 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 com.xebialabs.ci:xlrelease-plugin are affected by CVE-2022-34779? com.xebialabs.ci:xlrelease-plugin (maven) versions <= 22.0.0 is affected.
- Is there a fix for CVE-2022-34779? Yes. CVE-2022-34779 is fixed in 22.0.1. Upgrade to this version or later.
- Is CVE-2022-34779 exploitable, and should I be worried? Whether CVE-2022-34779 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-2022-34779 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-2022-34779? Upgrade
com.xebialabs.ci:xlrelease-pluginto 22.0.1 or later.
