Improper Authentication

CVE-2025-65431

Medium
5.4/10

Summary

An issue was discovered in django-allauth versions prior to 65.13.0. Both Okta and NetIQ were using "preferred_username" as the identifier for third-party provider accounts. That value may be mutable and should therefore be avoided for authorization decisions. The providers are now using "sub" instead.

CWE-287 - Improper Authentication

Improper (or broken) authentication attacks are widespread, and have accounted for many of the worst data breaches in recent years. Improper authentication attacks are a class of vulnerabilities where an attacker impersonates a legitimate user by exploiting weaknesses in either session management or credential management to gain access to the user’s account. This can result in disclosure of sensitive information, and can lead to system compromise, theft, identity theft, and fraud.
