## Technical details

A SQL injection vulnerability (CWE-89) exists in Django's QuerySet.annotate(), aggregate(), and extra() methods due to insufficient input validation of column alias names passed via keyword arguments. An attacker can exploit this by crafting a malicious dictionary with specially-crafted keys that bypass alias validation, allowing arbitrary SQL injection when the dictionary is expanded as **kwargs. This is a network-accessible vulnerability requiring no authentication or user interaction. Successful exploitation allows an attacker to execute arbitrary SQL queries, potentially leading to data exfiltration, modification, or deletion. Patches are available in Django 2.2.28, 3.2.13, and 4.0.4 or later.

## Affected products
