CVE-2020-7471

Severity CVSS v4.0:
Pending analysis
Type:
CWE-89 SQL Injection
Publication date:
03/02/2020
Last modified:
07/11/2023

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.
