[Salvatore Bonaccorso]

Source: python-django
Version: 2:2.2.9-2
Severity: grave
Tags: security upstream
Justification: user security hole
Control: found -1 1:1.11.27-1~deb10u1

Hi,

The following vulnerability was published for python-django.

CVE-2020-7471[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
