CVE-2026-108157
HighCVSS 8.1Summary
Pingvin Share X from 0.19.0 before 1.22.0 contains an improper authentication vulnerability allowing remote unauthenticated attackers to take over accounts. Attackers register a victim's unverified email on an enabled OAuth/OIDC provider, exploiting the missing email_verified check in GenericOidcProvider, to sign in as the victim including administrators while bypassing TOTP.
Risk Assessment
An attacker can take over any account, including administrative ones, leading to full platform compromise and access to all shared data.
Recommendation
Upgrade Pingvin Share X to version 1.22.0 or later and enforce email_verified checks in OAuth/OIDC provider configuration.

See all- CVE-2026-44196Critical
In Pingvin Share X versions 1.14.1 to 1.16.2, a critical authentication bypass vulnerability allows an attacker with a valid username and password to completely skip the two-factor authentication (TOTP) requirement. This vulnerability is fixed in version 1.16.3.
- CVE-2026-49467High
Pingvin Share X versions 1.5.0 through 1.18.0 contain a vulnerability that allows an attacker to bypass password verification when managing TOTP settings. The root cause is a missing `await` keyword on calls to asynchronous methods `verifyPassword` and `authenticateUser`. In JavaScript, an unawaited Promise is always truthy, so the logic intended to throw a ForbiddenException when a password is incorrect never executes. The vulnerability is fixed in version 1.18.1.
