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.

Affected products

• Django: from 1.11 before 1.11.28; from 2.2 before 2.2.10; from 3.0 before 3.0.3 — fixed in 1.11.28, 2.2.10, 3.0.3

How to fix

Upgrade to a fixed version: Django 1.11.28, 2.2.10, 3.0.3. Check the vendor advisory for mitigations.
