Summary
Sandbox bypass vulnerability through implicitly allowlisted platform Groovy files in Jenkins Pipeline: Groovy Plugin
Pipeline: Groovy Plugin allows pipelines to load Groovy source files. This is intended to be used to allow Global Shared Libraries to execute without sandbox protection.
In Pipeline: Groovy Plugin 2689.v434009a_31b_f1 and earlier, any Groovy source files bundled with Jenkins core and plugins could be loaded this way and their methods executed. If a suitable Groovy source file is available on the classpath of Jenkins, sandbox protections can be bypassed.
The Jenkins security team has been unable to identify any Groovy source files in Jenkins core or plugins that would allow attackers to execute dangerous code. While the severity of this issue is declared as High due to the potential impact, successful exploitation is considered very unlikely.
Pipeline: Groovy Plugin 2692.v76b_089ccd026 restricts which Groovy source files can be loaded in Pipelines.
Groovy source files in public plugins intended to be executed in sandboxed pipelines have been identified and added to an allowlist. The new extension point org.jenkinsci.plugins.workflow.cps.GroovySourceFileAllowlist allows plugins to add specific Groovy source files to that allowlist if necessary, but creation of plugin-specific Pipeline DSLs is strongly discouraged.
Impact
The application accepts file uploads without adequately restricting the file type or content. Typical impact: remote code execution if the uploaded file can be served and executed on the server.
CVE-2022-30945 has a CVSS score of 7.5 (High). 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 (2692.v76b); 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-2022-30945? CVE-2022-30945 is a high-severity unrestricted upload of dangerous file types vulnerability in org.jenkins-ci.plugins.workflow:workflow-cps (maven), affecting versions <= 2689.v434009a. It is fixed in 2692.v76b. The application accepts file uploads without adequately restricting the file type or content.
- How severe is CVE-2022-30945? CVE-2022-30945 has a CVSS score of 7.5 (High). 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.workflow:workflow-cps are affected by CVE-2022-30945? org.jenkins-ci.plugins.workflow:workflow-cps (maven) versions <= 2689.v434009a is affected.
- Is there a fix for CVE-2022-30945? Yes. CVE-2022-30945 is fixed in 2692.v76b. Upgrade to this version or later.
- Is CVE-2022-30945 exploitable, and should I be worried? Whether CVE-2022-30945 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-2022-30945 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.
