Critical Honeywell CCTV Flaw Exposes User Accounts

A recent advisory issued by CISA on February 17, 2026, highlights a severe security vulnerability in Honeywell CCTV products. Identified as CVE-2026-1670, this flaw could enable attackers to gain control over user accounts and access sensitive camera footage without authorization.

Understanding the Vulnerability

The security flaw, rated with a critical CVSS v3 score of 9.8, stems from a lack of authentication in a key function. This allows an unauthorized individual to alter the password recovery email linked to the device, bypassing the need for login credentials. Once the recovery email is changed to one under the attacker’s control, they can reset the password and seize the administrative account.

Potential Impact on Security

With administrative access, attackers not only compromise live video feeds but can also leverage this access point for further network intrusions. The vulnerability affects various Honeywell IP and PTZ camera models, including multiple versions widely used in commercial settings globally.

Security researcher Souvik Kandar identified and reported this flaw, emphasizing its potential impact on the commercial facilities sector. Although public exploitation has not been reported, the simplicity of the attack method necessitates prompt action.

Recommended Security Measures

CISA advises network administrators to reduce exposure of control systems. Ensuring these systems are not directly connected to the internet and are protected by firewalls is crucial. Control networks should remain isolated from business networks to prevent lateral threats.

For organizations relying on remote access, the use of secure technologies like updated Virtual Private Networks (VPNs) is recommended. Additionally, implementing social engineering defenses can help mitigate risks from phishing attacks, a common tactic used to gain initial unauthorized access.
