Summary
GeoServer prior to version 2.25.0 contains a reflected cross-site scripting (XSS) vulnerability in the WMS GetFeatureInfo HTML output format, enabling a remote attacker to execute arbitrary JavaScript code in a victim's browser via specially crafted SLD_BODY parameters. This issue has been patched in version 2.25.0.
Risk Assessment
An attacker can execute malicious script in the victim's browser context, potentially hijacking sessions or stealing data.
Recommendation
Update GeoServer to version 2.25.0 or later.
Other vulnerabilities in GeoServer
See all- CVE-2025-58360HighActively exploited
GeoServer is an open source server that allows users to share and edit geospatial data. From version 2.26.0 to before 2.26.2 and before 2.25.6, an XML External Entity (XXE) vulnerability was identified. The application accepts XML input through a specific endpoint /geoserver/wms operation GetMap. However, this input is not sufficiently sanitized or restricted, allowing an attacker to define external entities within the XML request. This issue has been patched in GeoServer 2.25.6, GeoServer 2.26.3, and GeoServer 2.27.0.
- CVE-2024-36401CriticalActively exploited
GeoServer versions prior to 2.22.6, 2.23.6, 2.24.4, and 2.25.2 allow unauthenticated remote code execution (RCE) through specially crafted OGC requests. The vulnerability stems from unsafely passing property names to the commons-jxpath library, which executes arbitrary code when evaluating XPath expressions. This affects all GeoServer instances, and exploitation has been confirmed via WFS, WMS, and WPS requests.
- CVE-2023-35042Critical
GeoServer 2, in some configurations, allows remote attackers to execute arbitrary code via java.lang.Runtime.getRuntime().exec in wps:LiteralData within a wps:Execute request.
- CVE-2025-58175Medium
GeoServer prior to versions 2.26.4 and 2.27.3 may allow an attacker to perform unauthenticated Server-Side Request Forgery (SSRF) using `ENTITY_RESOLUTION_ALLOWLIST`. This requires GeoServer to be configured to use a proxy base URL without a path or ending with a slash.
- CVE-2025-52465High
In GeoServer, prior to versions 2.26.4 and 2.27.3, a vulnerability exists that allows an authenticated administrator to pass arbitrary file names to the Master Password Dump web page, potentially creating files containing the master password in plaintext.
