CVE-2025-13473: Djangoproject Django

Medium severity, CVSS 5.3. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Djangoproject Django: from 4.2, before 4.2.28 (fixed in 4.2.28); from 5.2, before 5.2.11 (fixed in 5.2.11); from 6.0, before 6.0.2 (fixed in 6.0.2)
