Details

An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. django.utils.translation.check_for_language() is subject to a potential denial-of-service attack when given many distinct, very long language codes, which are retained as keys in an in-memory cache and consume process memory. Such codes reach the function through the django.views.i18n.set_language() view, which is not routed by default. The consumed memory is bounded, since request data is limited by the DATA_UPLOAD_MAX_MEMORY_SIZE setting (default 2.5 MB) and the cache holds a fixed maximum number of entries. Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected. Django would like to thank Jaeyoung Jang for reporting this issue.
