APITable through version 1.13.0-beta.1 contains a critical missing authentication vulnerability in its InternalUserController. Two endpoints, getUserHistories and closePausedUserAccount, are annotated with requiredLogin=false, allowing unauthenticated access. The nginx gateway proxies all /api requests to the backend, making these endpoints reachable by any unauthenticated client. An attacker can first enumerate accounts in the 30-day deletion cooling-off period, then permanently close those accounts by calling the closure endpoint. The account closure process irreversibly clears email addresses, phone numbers, nicknames, cancels space subscriptions, removes space memberships, and deletes OAuth bindings. This effectively bypasses the recovery window designed to let users reverse deletion requests, making account recovery impossible. The vulnerability poses a significant risk of mass account destruction by any unauthenticated attacker with network access to the gateway.
