CVE-2024-39614Network attack vector

Service interruption via unbounded language-code parsing

Published Jul 10, 2024 · Updated Nov 4, 2025

Denial of service in Django 4.2 before 4.2.14 and 5.0 before 5.0.7 allows remote attackers to interrupt applications via language codes. get_supported_language_variant() processes attacker-controlled, hyphen-rich language codes without a length limit, repeatedly deriving fallback variants and consuming resources. Reachability requires an application path that passes request-derived language codes to the helper, and exploitation affects availability without reported data disclosure or modification.
