GeoServer Zero-Day Targeted in Active Exploitation Attempts, Can Lead to RCE

A CVSS 9.8 SQL injection zero-day in GeoServer's PostGIS datastore enables RCE and drew active exploitation; fixes shipped in versions 3.0.1, 2.28.5, 2.27.6.

A SQL injection flaw in GeoServer's jsonArrayContains function within the GeoTools PostGIS datastore (GHSA-mqjf-5f49-2fjh, CVSS 9.8) was disclosed August 12, 2026, and saw hundreds of exploitation attempts within hours per watchTowr. An attacker-controlled value is interpolated into a PostgreSQL jsonb_path_exists() expression without escaping; with superuser or pg_execute_server_program privileges it escalates to OS command execution via WFS 1.0. GeoServer released versions 3.0.1, 2.28.5, and 2.27.6, and the flaw is a regression of CVE-2023-25158. GeoServer has a history of mass exploitation, including CVE-2024-36401 used for botnets and proxies.

    Unauthenticated RCE in OSGeo GeoServer via GeoTools XPath Injection
    OSGeo GeoServer ships the GeoTools library, which evaluates feature property names directly as XPath expressions without proper neutralization (CWE-95), so attacker-supplied input is executed as code rather than treated as data. A remote, unauthenticated attacker triggers the flaw by sending specially crafted requests to a GeoServer service, causing the injected expression to be evaluated in the server's context. Successful exploitation results in remote code execution on the host running GeoServer, giving the attacker control over the mapping server and any data or credentials it can reach. Any organization running GeoServer is affected, and the underlying GeoTools flaw also extends to dependent applications such as GeoNetwork, which shipped its own fix for an unauthenticated RCE chain affecting government geoportal backends. The flaw is being actively exploited: it was added to CISA KEV on 2024-07-15, and EPSS assigns a 99.8% probability of exploitation within 30 days.

    GeoTools is an open source Java library that provides tools for geospatial data.
    GeoTools is an open source Java library that provides tools for geospatial data. GeoTools includes support for OGC Filter expression language parsing, encoding and execution against a range of datastore. SQL Injection Vulnerabilities have been found when executing OGC Filters with JDBCDataStore implementations. Users are advised to upgrade to either version 27.4 or to 28.2 to resolve this issue. Users unable to upgrade may disable `encode functions` for PostGIS DataStores or enable `prepared statements` for JDBCDataStores as a partial mitigation.
