Description

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, when OAuth login was enabled with a provider that does not guarantee verified email addresses, an unauthenticated attacker could sign in as an existing user, potentially including a super admin, without knowing that user's password, because the application matched OAuth identities to accounts by email address alone. Exploitation requires OAuth to be explicitly enabled with such a provider. This issue is fixed in versions 5.74.1 and 6.24.0.
