CVE-2024-56329Network attack vector

Account takeover via unconfirmed OAuth account linking

Published Dec 20, 2024 · Updated Dec 24, 2024

Improper authentication in Socialstream before 6.2.0 allows remote attackers to hijack accounts through automatic OAuth account linking. AuthenticateOAuthCallback::authenticate directly passes the provider account returned by the callback to link when a user session exists, without obtaining consent. Exploitation requires an authenticated user to complete the OAuth callback; stateless Socialite configuration also removes state verification.
