Exploitation Probability (EPSS)

Low risk
0.19%

9th percentile - higher than 9% of all known CVEs

Summary

The GET /json/cfg endpoint in WLED calls serveJson without a settings-PIN check, unlike the /edit endpoint which checks correctPIN. This allows any unauthenticated client on the network to read the device's general configuration (network, hardware, LED setup).

Risk Assessment

Unauthorized access to device configuration may expose sensitive network and hardware details, potentially facilitating further attacks on the infrastructure.

Recommendation

Add a settings-PIN check to the /json/cfg endpoint, similar to /edit, and restrict access to authenticated clients only.

Original NVD description (English source)

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.
