Overview

CVE-2026-32666 is a high-severity vulnerability. It was published on March 21, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

WebCTRL systems that communicate over BACnet inherit the protocol's lack

of network layer authentication. WebCTRL does not implement additional

validation of BACnet traffic so an attacker with network access could

spoof BACnet packets directed at either the WebCTRL server or associated

AutomatedLogic controllers. Spoofed packets may be processed as

legitimate.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
