{"id":"CVE-2025-58175","aliases":["GHSA-x4r9-gmw3-hxww"],"url":"https://o3.security/vulnerability/CVE-2025-58175","summary":"GeoServer has a Server-Side Request Forgery (SSRF) Vulnerability in its XML Entity Resolution","details":"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.","published":"2026-06-18T14:31:19.757Z","modified":"2026-07-15T01:49:07.530585695Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:L"},"epss":{"score":0.00287,"percentile":0.20862,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.geoserver.web:gs-web-app","fixedVersion":"2.26.4"},{"ecosystem":"Maven","name":"org.geoserver:gs-main","fixedVersion":"2.26.4"},{"ecosystem":"Maven","name":"org.geoserver:gs-main","fixedVersion":"2.27.3"},{"ecosystem":"Maven","name":"org.geoserver.web:gs-web-app","fixedVersion":"2.27.3"}],"fix":{"url":"https://github.com/geoserver/geoserver/pull/8622","label":"geoserver/geoserver#8622"},"references":[{"type":"WEB","url":"https://osgeo-org.atlassian.net/browse/GEOS-11867"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/58xxx/CVE-2025-58175.json"},{"type":"ADVISORY","url":"https://github.com/geoserver/geoserver/security/advisories/GHSA-x4r9-gmw3-hxww"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-58175"},{"type":"FIX","url":"https://github.com/geoserver/geoserver/pull/8622"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:07.530585695Z"}}
