How to Fix CVE-2025-58175

To remediate this vulnerability, upgrade all affected Gs web app dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.geoserver.web:gs-web-app fixed: 2.26.4 
<dependency>
    <groupId>org.geoserver.web</groupId>

</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.geoserver.web

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-58175, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.geoserver.web

Analyze the terminal output to locate any version of Gs web app in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.26.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.geoserver.web command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Gs web app, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary A GeoServer that uses `ENTITY_RESOLUTION_ALLOWLIST` may allow attacker to perform unauthenticated Server-Side Request Forgery (SSRF). ### Details This vulnerability requires that GeoServer is set up to use a proxy base URL and the `ENTITY_RESOLUTION_ALLOWLIST` (default since 2.25.0): ### Impact This vulnerability allows an attacker to cause GeoServer to make requests to an unintended location. ### Workaround GeoServer installations are only affected by this vulnerability if they use a proxy base URL that does not contain a URL path or end with a slash (e.g., `https://somesite.org` instead of `https://somesite.org/` or `https://somesite.org/geoserver`). If the proxy base URL does not contain a path, adding a slash to the end of the URL will mitigate this vulnerability. ### Resources https://osgeo-org.atlassian.net/browse/GEOS-11867 https://github.com/geoserver/geoserver/pull/8622 ### Credits: - Le Mau Anh Phong at Verichains Cyber Force
