AI risk analysis

Summary
The flaw allows unauthenticated access to the device's configuration details via the GET /json/cfg endpoint, exposing sensitive information such as network settings and LED configurations.
Exploitability
Exploitation is relatively easy given that no authentication is required; an attacker on the same network can directly access this endpoint.
Blast radius
If exploited, attackers could gain insights into the device's setup, potentially leading to further attacks or unauthorized control of the device.
Prioritized remediation
Implement proper authentication checks for all configuration endpoints to prevent unauthorized access.

NVD description

WLED's GET /json/cfg endpoint (registered in wled00/wled_server.cpp) calls serveJson with no settings-PIN check, unlike the /edit endpoint which explicitly checks correctPIN, disclosing the device's general configuration (network, hardware, LED setup) to any unauthenticated client on the network.
