March 6th, 2026
Vulnerability Details
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Philips Hue Bridge. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the hk_hap_pair_storage_put function of the HomeKit implementation, which listens on TCP port 8080 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.
