CVE-2020-7471: Djangoproject Django

Critical severity, CVSS 9.8. EPSS: 65.6% chance of exploitation in the next 30 days.

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

• Djangoproject Django: from 1.11, before 1.11.28 (fixed in 1.11.28); from 2.2, before 2.2.10 (fixed in 2.2.10); from 3.0, before 3.0.3 (fixed in 3.0.3)
