NVD Description

Note: Versions mentioned in the description apply only to the upstream social-auth-core package and not the social-auth-core package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the partial-pipeline resume mechanism accepted partial_token as a bearer credential without binding it to the browser session that created it. Applications using resumable partial pipeline steps could allow an attacker to start an authentication flow, obtain a valid partial token and verification data, and cause a victim's browser to resume that attacker-controlled flow. This could authenticate the victim's browser as the attacker's account. The issue affects applications using partial pipeline steps such as mail_validation or custom steps decorated with @partial. The issue has been fixed in version 5.0.0 by binding partial pipeline resumes to the originating browser session.
