Summary
Django has Observable Timing Discrepancy
Details

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28.

The django.contrib.auth.handlers.modwsgi.check_password() function for authentication via mod_wsgi allows remote attackers to enumerate users via a timing attack. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.

Django would like to thank Stackered for reporting this issue.
