CVE-2021-45115

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.

UserAttributeSimilarityValidator incurred significant overhead evaluating submitted password that were artificially large in relative to the comparison values. On the assumption that access to user registration was unrestricted this provided a potential vector for a denial-of-service attack. (CVE-2021-45115) Due to leveraging the Django Template Language's variable resolution logic, the dictsort template filter was potentially vulnerable to information disclosure or unintended method calls, if passed a suitably crafted key. (CVE-2021-45116) Storage.save() allowed directory-traversal if directly passed suitably crafted file names. (CVE-2021-45452)
