HIGH
Denial-of-service in Django
Published January 12, 2022Updated September 20, 2024Source: osv
Details
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.

pip
Update django to 2.2.26 or laterpip install "django>=2.2.26"
pip
Update django to 4.0.1 or laterpip install "django>=4.0.1"
After upgrading, run your dependency scanner again to confirm the vulnerability is resolved.
