Account impersonation via case-insensitive UID lookup
Published Apr 24, 2024 · Updated Aug 2, 2024
Case-insensitive UID matching in Python Social Auth social-auth-app-django before 5.4.1 allows remote authenticated users to access another account. The UserSocialAuth.get_social_auth method passes the provider and untrusted third-party UID to a database equality filter, so default MySQL or MariaDB collation treats case-distinct identifiers as equal; the patched code verifies the returned UID with a case-sensitive Python comparison. Exploitation requires a third-party login whose UID differs only by letter case from a victim's UID, enabling access to the victim-linked application account without interrupting service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <5.4.1
