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.
AnalysisAI
Pingvin Share X versions 1.5.0 through 1.18.0 expose an authentication bypass in TOTP management endpoints due to a JavaScript async/await coding defect. An authenticated attacker with a low-privileged account can modify or disable TOTP two-factor authentication settings on an account without supplying a correct password, effectively neutralizing 2FA protections. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated user account on the target Pingvin Share X instance (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) accurately reflects network accessibility and low-complexity exploitation but warrants nuance. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Pingvin Share X version 1.18.1, which resolves the issue by adding the missing `await` keyword to all asynchronous authentication calls in `authTotp.service.ts` and `auth.service.ts`. … Detailed patch versions, workarounds, and compensating controls in full report. |
