CVE-2021-45115
HIGH7.5EPSS 0.41%Denial-of-service in Django
發布日:2022/1/12修改日:2024/9/20
描述
An issue was discovered in Django 2.2 before 2.2.26, 3.2 before 3.2.11, and 4.0 before 4.0.1. `UserAttributeSimilarityValidator` incurred significant overhead in evaluating a submitted password that was artificially large in relation to the comparison values. In a situation where access to user registration was unrestricted, this provided a potential vector for a denial-of-service attack.
