Philips Hue Bridge HomeKit Accessory Protocol Transient Pairing Mode 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 HomeKit Accessory Protocol service, which listens on TCP port 8080 by default. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-28374.
AnalysisAI
The Philips Hue Bridge HomeKit Accessory Protocol (HAP) service on TCP port 8080 lacks authentication in transient pairing mode, allowing network-adjacent attackers to bypass authentication and gain unauthorized access without requiring credentials (CVE-2026-3558, CVSS 8.1). This vulnerability affects all versions of Philips Hue Bridge and has been tracked as ZDI-CAN-28374. …

Vulnerability AssessmentAI
| Exploitation | Philips Hue Bridge with HomeKit Accessory Protocol service listening on TCP port 8080 (default configuration). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.1 score reflects high severity with network-adjacent access (AV:A), low attack complexity (AC:L), no privilege requirements (PR:N), and no user interaction needed (UI:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with access to the same local network as the Philips Hue Bridge (e.g., on the victim's home Wi-Fi, guest network, or corporate office network) sends unauthenticated HAP commands directly to TCP port 8080. Due to the lack of authentication checks in transient pairing mode, the bridge accepts requests to enumerate paired devices, read sensor data (motion, temperature, brightness), and execute control commands (turn lights on/off, change colors, trigger automation scenes). … |
| Remediation | 1. … Detailed patch versions, workarounds, and compensating controls in full report. |
