Missing Authentication in Honeywell CCTV Password Recovery API

IdentifiersCVE-2026-1670CWE-306· Missing Authentication for…

CVE-2026-1670 is a critical missing-authentication vulnerability in multiple Honeywell CCTV products. The issue is caused by exposure of an unauthenticated API endpoint tied to the device's "forgot password" workflow. An attacker can remotely invoke this endpoint without valid credentials to change the password recovery email address associated with the device account. After replacing the recovery address with one under attacker control, the attacker can trigger the password reset process and obtain administrative control of the affected device. Reported affected products include Honeywell I-HIB2PI-UL 2MP IP version 6.1.22.1216 and several camera lines running firmware WDR_2MP_32M_PTZ_v2.0, including SMB NDAA MVO-3, PTZ WDR 2MP 32M, and 25M IPC. CISA characterizes the flaw as "missing authentication for critical function" and assigns CVSS v3.1 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can lead to full account takeover of the affected CCTV device by allowing an attacker to redirect password recovery to an attacker-controlled email address and reset the administrative password. This can provide unauthorized access to camera feeds and device management functions. The advisory material also notes the compromised device could serve as a pivot point for broader network compromise, particularly where surveillance devices are reachable from enterprise or operational networks.

Mitigation

If you can’t patch tonight, do this now.

Until patches are available, minimize exposure of affected cameras and ensure they are not directly accessible from the Internet. Place devices behind firewalls, isolate them from business networks through segmentation, and restrict management access to trusted networks only. Where remote access is required, use secure VPN-based access and keep VPN infrastructure updated. Perform impact analysis and risk assessment before operational changes in ICS/OT environments.

Remediation

Patch, then assume compromise.

Apply Honeywell firmware updates or vendor-provided fixes when available. Content provided indicates Honeywell stated that no fix was currently available for I-HIB2PI-UL at the time of its notice and that a patch was being developed. Organizations should contact Honeywell support for model-specific patch guidance and update affected devices promptly once corrected firmware is released.
