Authentication bypass via static SRP nonce
Published Mar 13, 2026 · Updated Mar 13, 2026
Authentication bypass in Signify Philips Hue Bridge 1.73.1973146020 allows network-adjacent attackers to bypass system authentication. The HomeKit Accessory Protocol service on TCP port 8080 configures SRP with a static nonce instead of a fresh value for each exchange. Exploitation requires adjacent-network access but no credentials or user interaction, enabling unauthorized access to protected HomeKit operations without reported service interruption.
