Summary
GeoServer Infinite Loop Vulnerability in Jiffle process
Full technical description
Malicious Jiffle scripts can be executed by GeoServer, either as a rendering transformation in WMS dynamic styles or as a WPS process, that can enter an infinite loop to trigger denial of service.
Details
The Jiffle language supports multiple loop constructs that will cause its code block to be continuously executed until a certain condition is met. The Jiffle runtime should be updated to throw an exception if the script exceeds a certain number of loop iterations.
Mitigation
This vulnerability can be mitigated by disabling WMS dynamic styling (see WMS Settings).
If the WPS extension is installed, the Jiffle process must also be disabled to mitigate this vulnerability (see WPS Settings)

Impact
This vulnerability allows attackers to conduct denial-of-service attacks.
CVE-2025-30145 has a CVSS score of 7.5 (High). The vector is network-reachable, no 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 (2.26.3, 2.25.7); 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-2025-30145? CVE-2025-30145 is a high-severity security vulnerability in org.geoserver.web:gs-web-app (maven), affecting versions >= 2.26.0, <= 2.26.2. It is fixed in 2.26.3, 2.25.7.
- How severe is CVE-2025-30145? CVE-2025-30145 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 packages are affected by CVE-2025-30145?
org.geoserver.web:gs-web-app(maven) (versions >= 2.26.0, <= 2.26.2)org.geoserver:gs-wms(maven) (versions >= 2.26.0, <= 2.26.2)org.geoserver.extension:gs-wps-core(maven) (versions >= 2.26.0, <= 2.26.2)
- Is there a fix for CVE-2025-30145? Yes. CVE-2025-30145 is fixed in 2.26.3, 2.25.7. Upgrade to this version or later.
- Is CVE-2025-30145 exploitable, and should I be worried? Whether CVE-2025-30145 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-2025-30145 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.
