NewCVE-2026-77050 (opens in a new tab)How to fix?
Upgrade Django to version 5.2.18, 6.0.9, 6.1.2 or higher.
Overview
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value due to the get_supported_language_variant() function in django/utils/translation/trans_real.py. An attacker can exhaust process memory by sending many distinct, very long language codes that are cached as lru_cache keys before the length check is applied. This can grow the in-memory cache with attacker-controlled values and degrade or crash a Django process handling requests that supply language codes.
