  "title": "Email verification token binding flaw in Pocket ID backend",
  "summary": "Pocket ID backend versions 2.2.0 through before 2.12.0 can mark a changed account email address as verified using a token issued for the prior address. An authenticated user who can edit their own account can falsely obtain a verified-email claim for an unassigned address; impact on other applications requires them to trust that claim for email-based account matching or provisioning.",
  "mitigation": "Upgrade Pocket ID backend to v2.12.0. Until upgraded, restrict user email changes and avoid using verified email claims as the sole basis for account linking or provisioning.",
