CVE-2026-44196: CWE-287: Improper Authentication in smp46 pingvin-share-x
Pingvin Share X versions 1. 14. 1 through 1. 16. 2 contain a critical authentication bypass vulnerability that allows an attacker with a valid username and password to bypass the second-factor authentication (TOTP). This flaw enables skipping the 2FA step entirely, reducing the security of accounts relying on multi-factor authentication. The vulnerability is fixed in version 1. 16. 3.
AI Analysis
Technical Summary
CVE-2026-44196 is an authentication bypass vulnerability (CWE-287) in Pingvin Share X, a self-hosted file sharing platform by smp46. In affected versions from 1.14.1 up to but not including 1.16.3, an attacker who has obtained valid user credentials can bypass the Time-based One-Time Password (TOTP) second-factor authentication requirement. This means that possession of the password alone is sufficient to authenticate without completing the 2FA step. The vulnerability was addressed and fixed in version 1.16.3.
Potential Impact
The vulnerability allows attackers who have valid usernames and passwords to bypass the second-factor authentication, effectively reducing the security of accounts protected by TOTP 2FA. This increases the risk of unauthorized access to user accounts and potentially sensitive shared files. The CVSS score of 9.1 reflects the critical severity due to the ease of network exploitation and high impact on confidentiality and integrity.
Mitigation Recommendations
Upgrade Pingvin Share X to version 1.16.3 or later, where this authentication bypass vulnerability is fixed. No other mitigation is indicated or effective since the issue is resolved by the official patch.
