Technical Details
The vulnerability (CVE-2026-1670) stems from a missing authentication mechanism for a critical API endpoint in Honeywell CCTV products. This flaw allows attackers to remotely modify the "forgot password" recovery email address without requiring prior authentication. Once the recovery email is changed, attackers can initiate password reset requests, gain control of user accounts, and access live camera feeds.
#### Vulnerability Classification
- CWE-306: Missing Authentication for Critical Function
- CVSS 3.1 Base Score: 9.8 (Critical)
- Vector String: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
This classification indicates that the vulnerability is easily exploitable over a network, requires no privileges or user interaction, and has a severe impact on confidentiality, integrity, and availability.
