CVE-2026-107640 [CRITICAL] – Integrics Enswitch 3.13 through 4.4 contains an authentication bypass vulnerability in /ap

Integrics Enswitch 3.13 through 4.4 contains an authentication bypass vulnerability in /api/json/user/password/update/ that allows unauthenticated attackers to change account passwords by omitting the reset parameter. Attackers can target accounts with no pending reset, whose empty reset_key matches the defaulted empty value, to take over administrator accounts after enumerating valid usernames.
