SQL injection via unchecked JSONField column alias
Published Aug 7, 2024 · Updated Nov 4, 2025
SQL injection in Django 4.2 before 4.2.15 and 5.0 before 5.0.8 allows attackers to alter database queries via crafted JSON keys. Query.set_values() accepted positional JSONField paths without applying check_alias(), so whitespace, quotes, semicolons, or SQL comments in a JSON key reached a column alias. Reachability requires application code to pass an attacker-controlled JSON object key as a positional argument to QuerySet.values() or values_list(); injected SQL then runs with the application's database permissions.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=4.2 <4.2.15
- Affected versionversion=5.0 <5.0.8
