CVE-2020-13254: Data leakage via cache key collision in Django
(updated )
An issue was discovered in Django version 2.2 before 2.2.13 and 3.0 before 3.0.7. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage.
