CVE-2019-14234 Information

Description

An issue was discovered in Django 1.11.x before 1.11.23 2.1.x before 2.1.11 and 2.2.x before 2.2.4. Due to an error in shallow key transformation key and index lookups for django.contrib.postgres.fields.JSONField and key lookups for django.contrib.postgres.fields.HStoreField were subject to SQL injection. This could for example be exploited via crafted use of \OR 1=1\ in a key or index name to return all records using a suitably crafted dictionary with dictionary expansion as the **kwargs passed to the QuerySet.filter() function.
