SQL injection via unchecked alias control characters
Published Feb 3, 2026 · Updated Feb 3, 2026
SQL injection in Django 4.2 before 4.2.28, 5.2 before 5.2.11, and 6.0 before 6.0.2 allows attackers to alter SQL queries. Query.check_alias omits C0 and C1 control characters from its forbidden-alias pattern, allowing them into FilteredRelation aliases supplied by dictionary expansion to ORM QuerySet methods. Exploitation requires a consuming application to pass attacker-influenced dictionary keys as keyword aliases; resulting queries execute with the application's database privileges.
