      "title": "MISP Missing Authorization in Cryptographic Key View Exposes Signing Keys from Protected Events",
      "summary": "Affected versions of MISP do not enforce parent-event visibility when serving cryptographic keys through CryptographicKeysController::view().\n\n\nThe vulnerable handler queried CryptographicKey directly using the supplied key ID and selected sensitive fields such as:\n\n\n\n  *  \ntype\n\n\n  *  \nkey_data\n\n\n  *  \nfingerprint\n\n\n\n\n\nbut did not fetch or authorize the associated parent event first.\n\n\nThe upstream commit explicitly states that cryptographicKeys/view could return a protected event’s signing key to any authenticated user.\n\n\nThe fix adds parent_id and parent_type to the lookup and then enforces authorization through the associated event using fetchSimpleEvent($user, parent_id). If the parent is not an Event, access is limited to site administrators.\n\nVersion affected: ≤2.5.45",
