0 mediasoup versions 3.20.0 through 3.20.6 (npm) and 0.22.0 through 0.22.5 (Rust crate) contain an insufficient verification of data authenticity vulnerability in their SCTP stack. The built-in SCTP stack uses hardcoded magic values instead of a per-instance secret and HMAC to authenticate state cookies, allowing an on-path attacker targeting PlainTransport or PipeTransport with SCTP enabled and no DTLS protection to forge a valid COOKIE-ECHO packet. This enables unauthorized SCTP association establishment and DataChannel message injection as a trusted peer. WebRtcTransport is not affected as its SCTP runs inside DTLS. The issue is fixed in npm version 3.20.6 and Rust crate version 0.22.5. Join the discussion | CVE Database V5 | 08/25/2026, 18:15:16 UTC Added: 08/25/2026, 18:38:59 UTC |
