  "title": "OIDC email-verification authentication bypass in Databasement",
  "summary": "Databasement versions before 1.10.9 can associate an OIDC identity with a local account without verifying ownership of the email address. An attacker able to create an identity-provider account using a target's unverified email address could access that target's account, including an administrator account.",
  "mitigation": "Upgrade Databasement to version 1.10.9 or later. Ensure OIDC login processing requires verified email claims before linking identities to existing local users.",
