No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Weak encryption in the Quick Pairing mode in the eWeLink mobile application (Android application V4.9.2 and earlier, iOS application V4.9.1 and earlier) allows physically proximate attackers to eavesdrop on Wi-Fi credentials and other sensitive information by monitoring the Wi-Fi spectrum during the pairing process.
