CVE-2026-3559

Estado: AnalizadaAlta (8.1)—

Philips Hue Bridge HomeKit Accessory Protocol Static Nonce Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Philips Hue Bridge. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the configuration of the SRP authentication mechanism in the HomeKit Accessory Protocol service, which listens on TCP port 8080 by default. The issue results from the use of a static nonce value. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-28451.
