CVE-2025-61783
Python Social Auth - Django has unsafe account association
Impact
### Impact 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. ### Patches * https://github.com/python-social-auth/social-app-django/pull/803 ### Workarounds Review the authentication service policy on e-mail addresses; many will not allow exploiting this vulnerability.
