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.

A SQL Injection vulnerability (CVE-2026-76904) has been identified in GeoTools, an open source Java geospatial library. The vulnerability exists in the `jsonArrayContains` function within the PostGIS DataStore implementation when executing OGC Filters. Affected versions start from 30.5 up to (but not including) 33.6, 34.5, and 35.1. The flaw occurs because the `<value>` parameter is written into generated SQL without proper escaping, enabling potential SQL injection attacks. Exploitation requires PostGIS version 12 or greater with a String or JSON field. Patches have been released in versions 33.6, 34.5, and 35.1. No known workarounds exist, though limiting the PostGIS connection pool permissions can reduce the attack scope. Users are strongly advised to upgrade to a patched version immediately.
