CVE-2025-61783
Python Social Auth - Django has unsafe account association
Description
Python Social Auth is a social authentication/registration mechanism. In versions prior to 5.6.0, upon authentication, the user could be associated by e-mail even if the `associate_by_email` pipeline was not included. This could lead to account compromise when a third-party authentication service does not validate provided e-mail addresses or doesn't require unique e-mail addresses. Version 5.6.0 contains a patch. As a workaround, review the authentication service policy on e-mail addresses; many will not allow exploiting this vulnerability.

Action Type Old Value New Value Added Translation Title: social-app-django de python-social-auth, Description: Python Social Auth es un mecanismo de autenticación/registro social. En versiones anteriores a la 5.6.0, tras la autenticación, el usuario podía ser asociado por correo electrónico incluso si el pipeline 'associate_by_email' no estaba incluido. Esto podría llevar al compromiso de la cuenta cuando un servicio de autenticación de terceros no valida las direcciones de correo electrónico proporcionadas o no requiere direcciones de correo electrónico únicas. La versión 5.6.0 contiene un parche. Como solución alternativa, revise la política del servicio de autenticación sobre las direcciones de correo electrónico; muchos no permitirán explotar esta vulnerabilidad. -
