CVE-2026-44196Network attack vector

Account access via incorrect TOTP result comparison

Published May 12, 2026 · Updated May 12, 2026

Authentication bypass in Pingvin Share X 1.14.1 through 1.16.2 allows remote authenticated users to access TOTP-protected accounts. The TOTP login service tests the verification result object itself instead of its valid property, so every six-digit code passes the check. A valid username and password for a TOTP-enabled user are required; successful login permits share management, sensitive-file access, and account-setting changes.
