Vulnerability Title
GeoTools has unauthenticated SQL injection in the jsonArrayContains filter function against PostGIS layers
Source: CVE Program / CVE List V5
Vulnerability Description
GeoTools is an open source Java library that provides tools for geospatial data. Starting in version 30.5 and prior to versions 33.6, 34.5, and 33.6, an SQL Injection Vulnerability is present when executing OGC Filters with PostGIS DataStore implementation: `jsonArrayContains` function; Requires PostGIS 12 or greater with a String or JSON field. For PostGIS 12 and greater `jsonArrayContains(<column>, <pointer>, <value>)` function writes `<value>` into generated SQL without escaping. Patches are available in versions 33.6, 34.5, and 33.6. No known workaround is available. To limit scope of SQL Injection the PostGIS connection pool should be configured with limited rights.

II. Public POCs for CVE-2026-76904

# POC Description Source Link Shenlong Link
1 GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. GeoTools FilterToSqlHelper.constructEquality writes the expected argument of the jsonArrayContains CQL function RAW into the SQL string while only escaping the JSON pointer. A single quote in the value parameter breaks out of the PostgreSQL jsonb_path_exists string literal, enabling unauthenticated SQL injection. When the PostGIS backend runs with superuser privileges, the injection escalates to operating system command execution through PostgreSQL COPY TO PROGRAM. Users are advised to upgrade to either version 2.21.4, or version 2.22.2 to resolve this issue. Users unable to upgrade should enable the PostGIS DataStore preparedStatements setting and disable encode functions as a workaround. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-76904.yaml POC Details
