Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The social-auth-core package, versions before 5.0.0, is vulnerable to login CSRF in its LoginRadius backend, which did not validate the OAuth state during authentication. An attacker can get a victim's browser session to complete login with an attacker-controlled LoginRadius token, authenticating the victim as the attacker's identity. Upgrade to version 5.0.0 or later; disabling the LoginRadius backend by removing it from SOCIAL_AUTH_AUTHENTICATION_BACKENDS is the only workaround, and it is only available if the backend is not needed.
