Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GeoServer, in the gs-wfs and gs-app Maven packages, versions from 2.0.0 before 2.24.4 and from 2.25.0 before 2.25.2, is vulnerable to server-side request forgery through the Demo request endpoint (TestWfsPost) when Proxy Base URL is not set. An unauthenticated attacker can make the server issue requests, which can be used to probe internal networks and, on cloud instances, to reach sensitive data. Upgrade to 2.24.4 or 2.25.2, which removes the servlet. If upgrading is not possible, set a non-empty PROXY_BASE_URL value that users cannot override, or block access to TestWfsPost in web.xml.
