Upgrade social-auth-core to version 5.0.0 or higher.
Overview
social-auth-core is a package that makes Python social authentication simple.
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) via the LoginRadiusAuth backend in social_core/backends/loginradius.py, which sets REDIRECT_STATE = False and STATE_PARAMETER = False, disabling OAuth2 state parameter validation entirely. An attacker can perform a login CSRF attack by tricking a victim into completing an OAuth2 flow that the attacker initiated, allowing the attacker to associate the victim's browser session with an account the attacker controls.
