How to Fix CVE-2025-27505

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: 2.26.3 
<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-2025-27505, 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 2.26.3), 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. 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 It is possible to bypass the default REST API security and access the index page. ### Details The REST API security handles `rest` and its subpaths but not `rest` with an extension (e.g., `rest.html`). ### Impact The REST API index can disclose whether certain extensions are installed. ### Workaround In `${GEOSERVER_DATA_DIR}/security/config.xml`, change the paths for the `rest` filter to `/rest.*,/rest/**` and change the paths for the `gwc` filter to `/gwc/rest.*,/gwc/rest/**` and restart GeoServer. ### References https://osgeo-org.atlassian.net/browse/GEOS-11664 https://osgeo-org.atlassian.net/browse/GEOS-11776 https://github.com/geoserver/geoserver/pull/8170
