Overview

gt-jdbc-postgis SQL Injection

### Summary

An SQL Injection Vulnerability has been found 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

* GeoTools 35.1 * GeoTools 33.5 * GeoTools 34.4

### Mitigation

No mitigation is available:

* To limit scope of SQL Injection the PostGIS connection pool should be configured with limited rights.

### Impact

This vulnerability can lead to execution of arbitrary SQL expressions in the database.
