Vulnerability in ex_webrtc (CVE-2026-44700)
Summary
Vulnerability in ex_webrtc (CVE-2026-44700). Risk of unauthorized operations or information disclosure. Exploitable via ex_webrtc. Mitigation: upgrade to 0.16.1 or later.
Original description
The description as published by the source.
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 standard deployments, but enables a full man-in-the-middle attack when chained with insecure signalling or a peer with similar validation gaps. This vulnerability is fixed in 0.15.1 and 0.16.1.
