CVE-2026-44700 Elixir WebRTC: Missing DTLS peer fingerprint validation in ex_webrtc client-role handshake
Elixir WebRTC is an Elixir implementation of the W3C WebRTC API. Prior to 0.15.1 and 0.16.1, missing DTLS peer certificate fingerprint validation in the DTLS client active role removes one side of WebRTC's mutual authentication. The bug is not independently exploitable for media interception in...
CVE-2026-44700
CVE-2026-44700 affects the Elixir WebRTC project (ex_webrtc). Before versions 0.15.1 and 0.16.1, the DTLS fingerprint validation was skipped when the DTLS client acts as the active party during handshake, effectively removing one side of WebRTC’s mutual authentication. This does not by itself ena...
