• Severity: critical (CVSS 9.8 v3.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 47.7% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2019-08-09 · updated 2026-06-17
• Weakness: CWE-89

Description

An issue was discovered in Django 1.11.x before 1.11.23, 2.1.x before 2.1.11, and 2.2.x before 2.2.4. Due to an error in shallow key transformation, key and index lookups for django.contrib.postgres.fields.JSONField, and key lookups for django.contrib.postgres.fields.HStoreField, were subject to SQL injection. This could, for example, be exploited via crafted use of "OR 1=1" in a key or index name to return all records, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to the QuerySet.filter() function.

Affected products

• Django: from 1.11 before 1.11.23; from 2.1 before 2.1.11; from 2.2 before 2.2.4 — fixed in 1.11.23, 2.1.11, 2.2.4
• Fedoraproject Fedora: 30
