CVE-2025-65431: django-allauth's Okta and NetIQ implementations used a mutable identifier for authorization decisions

December 15, 2025 (updated December 16, 2025)

An issue was discovered in allauth-django before 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.
