CVE-2020-7471 Information

Description

Django 1.11 before 1.11.28 2.2 before 2.2.10 and 3.0 before 3.0.3 allows SQL Injection if untrusted data is used as a StringAgg delimiter (e.g. in Django applications that offer downloads of data as a series of rows with a user-specified column delimiter). By passing a suitably crafted delimiter to a contrib.postgres.aggregates.StringAgg instance it was possible to break escaping and inject malicious SQL.
