CVE-2025-58175
GeoServer has a Server-Side Request Forgery (SSRF) Vulnerability in its XML Entity Resolution
GeoServer is an open source server that allows users to share and edit geospatial data. Prior to versions 2.26.4 and 2.27.3, a GeoServer that uses ENTITY_RESOLUTION_ALLOWLIST may allow attacker to perform unauthenticated Server-Side Request Forgery (SSRF). This vulnerability requires that GeoServer is set up to use a proxy base URL and the ENTITY_RESOLUTION_ALLOWLIST (default since 2.25.0). Versions 2.26.4 and 2.27.3 contain a fix. 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. If the proxy base URL does not contain a path, adding a slash to the end of the URL will mitigate this vulnerability.

GeoServer has a Server-Side Request Forgery (SSRF) Vulnerability in its XML Entity Resolution
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.
