What is CVE-2025-61783?

Python Social Auth, a mechanism for social authentication and registration, contains a vulnerability in versions prior to 5.6.0. During the authentication process, users can be associated with accounts via email even if the associate_by_email pipeline is not included. This flaw may result in account compromise, particularly when third-party authentication services fail to validate email addresses or enforce unique emails. The issue is addressed in version 5.6.0, and users are advised to check their authentication service policies regarding email usage as a workaround.
