CVE-2026-71231Public exploitNetwork attack vector

Authentication bypass via lastLogin cookie SQL injection

Published Aug 5, 2026 · Updated Aug 5, 2026

SQL injection in IOTSmartHome 0 allows remote attackers to bypass authentication and read database contents through a crafted lastLogin cookie. The checkCookie() function decodes the client-controlled cookie and concatenates the result into a users-table query without neutralizing SQL syntax. No account or user interaction is required; successful UNION-based injection exposes stored data, including credentials.
