CVE-2021-45115 (GCVE-0-2021-45115)

Vulnerability from cvelistv5 – Published: 2022-01-04 23:16 – Updated: 2024-08-04 04:39

Summary

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.

Severity

No CVSS data available.
