CVE-2026-45327Network attack vector

Unauthenticated stream injection via WebRTC source offer

Published Jun 5, 2026 · Updated Jun 5, 2026

Missing authentication in TinyIce 0.8.95 through 2.4.1 allows remote attackers to inject audio or video into a named WebRTC mount. The POST /webrtc/source-offer handler passes an unauthenticated SDP offer to WebRTCManager.HandleSourceOffer, which publishes the offered tracks. Any attacker who can reach the TinyIce HTTP port can replace a mount's intended broadcast for its listeners and repeatedly disrupt the legitimate source.
