## Description

Pingvin Share X is a secure and easy self-hosted file sharing platform. A vulnerability in versions 1.5.0 through 1.18.0 allow an attacker to bypass password verification when managing Time-based One-Time Password (TOTP) settings. The root cause is a missing `await` keyword on calls to the asynchronous `verifyPassword` method in `authTotp.service.ts` and the `authenticateUser` method in `auth.service.ts`. In JavaScript, an unawaited `Promise` is always truthy. So the logic intended to throw a `ForbiddenException` when a password is incorrect. It never executes because the expression evaluates the existence of the `Promise` object rather than its resolved boolean result. The vulnerability is fixed in version 1.18.1 by ensuring all asynchronous authentication calls are properly awaited. There are no official workarounds. If a user is locked out, an administrator must manually reset the user's TOTP status in the database.
