    "summary": "An authorization vulnerability exists in the country or region configuration interface of TP-Link RE305 V3. An unauthenticated attacker on the same local network may modify the wireless regulatory region and force the device to reapply its wireless configuration. Successful exploitation may cause wireless connection interruptions, unavailable channels, client disconnections, or wireless service instability, and may cause the device to apply parameters intended for a different regulatory region.",
