CVE-2026-121939 Details
Description
Databasement before 1.10.9 contains an authentication bypass vulnerability in OAuthService::findOrCreateLocalUser() that links OIDC identities to local users by email without checking email_verified. Attackers can register an identity provider account with a victim's unverified email to log in as any user, including the super-admin, and retain access after password resets.
A vulnerability allowing authentication bypass has been identified in Databasement versions prior to 1.10.9. The issue arises in the OAuthService::findOrCreateLocalUser() method, where OpenID Connect (OIDC) identities are linked to local users based on email addresses without verifying if the email has been confirmed. This flaw enables attackers to create accounts with unverified emails on the identity provider (IdP) and log in as any user, including super-admins, while maintaining access after password resets.
Users can update to Databasement version 1.10.9 or later, where this vulnerability has been fixed.
