CVE-2026-31903 Details
Description
The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
A vulnerability exists in the WebSocket API of Automated Logic WebCTRL Premium Server, specifically in versions prior to 8.5 cumulative releases. The issue arises from a lack of rate limiting on authentication requests, which could enable an attacker to perform denial-of-service attacks by disrupting legitimate charger telemetry or to conduct brute-force attacks to gain unauthorized access.
For customers using supported versions of WebCTRL (WebCTRL 8.5 cumulative releases and later), Automated Logic provides secure configuration guidance for hardware and software deployments, BACnet Secure Connect support, and published best practices for network segmentation, access control, and secure protocol implementation. Additional information is available on the Automated Logic website.
