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.
