CVE-2026-38740Public exploitNetwork attack vector

ICE credential disclosure via cleartext RTC signaling

Published May 14, 2026 · Updated May 14, 2026

Cleartext transmission in Foscam VD1 Video Doorbell before 5.3.13_1072 allows remote attackers to obtain ICE credentials from RTC traffic. The RTC signaling layer sends SDP containing ICE usernames, passwords, and routing candidates without TLS encryption or integrity protection. Network visibility is required; captured credentials permit media interception and authentication to Foscam TURN relays for arbitrary traffic forwarding.
