CVE-2026-126150: Fortinet FortiMail weak password recovery authentication bypass

CVE-2026-126150 · Severity: critical · CVSS 9.1 · Published 2026-11-11

FortiMail is an email security appliance that protects organizations from email-based threats. An unauthenticated attacker can reset the password of any IBE webmail user account and take complete control of it by sending specially crafted HTTP requests, bypassing the password recovery authentication entirely. This allows account takeover without any legitimate access or knowledge of the original password.
