Last modified Jun 17, 2026

CVE-2020-7471 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 65.34% chance of exploitation in the next 30 days.
