CVE-2020-13254
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.
Does this matter?
Lower severity and a low EPSS score (6.09%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in Django 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.
