CVE-2026-44700

High
Published: Translated: NVD NIST

Summary

Elixir WebRTC, an Elixir implementation of the W3C WebRTC API, had an issue with missing DTLS peer certificate fingerprint validation in the DTLS client (active) role prior to versions 0.15.1 and 0.16.1. This bug weakens WebRTC's mutual authentication, potentially allowing a man-in-the-middle attack when combined with insecure signaling.

Risk Assessment

The lack of certificate validation may allow an attacker to intercept communications if other security gaps are exploited. Organizations should be aware of the risk of unauthorized access to data transmitted via WebRTC.

Recommendation

It is recommended to upgrade to versions 0.15.1 or 0.16.1 to mitigate this vulnerability. Additionally, ensure that signaling is properly secured.

Original NVD description (English 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.
