Prior to 6.0.28, the @libp2p/webrtc webRTCDirect() Node.js listener processes unauthenticated STUN Binding Requests before PeerId authentication, Noise, muxing, protocol negotiation, connection creation, or connection-manager admission. The listener in packages/transport-webrtc/src/private-to-public/utils/stun-listener.ts forwards the packet-controlled request.ufrag into DirectRTCPeerConnection.setLocalDescription, where the value is reused as an ICE password without validating its required length and character set. A short credential causes node-datachannel or libdatachannel to raise an uncaught native invalid_argument and abort the process with SIGABRT, allowing a single remote UDP packet to deny service. The confirmed impact is process termination only, with no demonstrated memory corruption, code execution, browser impact, confidentiality impact, integrity impact, or connection-limit bypass. This issue is fixed in version 6.0.28.\nhttps://www.cve.org/CVERecord?id=CVE-2026-103936https://github.com/libp2p/js-libp2p/security/advisories/GHSA-x3m2-6mg8-vj7fhttps://github.com/libp2p/js-libp2p/pull/3584https://github.com/libp2p/js-libp2p/commit/68794c8e2e67d5f38da59e379dc051b2789e46f6https://github.com/libp2p/js-libp2p/releases/tag/webrtc-v6.0.28#libp2p #js-libp2p #@libp2p #webrtc#CVE_2026_103936#bot", "url": "https://infosec.exchange/users/cve/statuses/117446118753806378"}, {"timestamp": "2026-10-15T18:17:22.433Z", "date_only": false, "value": "2026-10-15T18:17:22.433", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-103936", "record": "FKIE_CVE-2026-103936", "field": "published"}, {"timestamp": "2026-10-15T18:48:15.889Z", "date_only": false, "value": "2026-10-15T18:48:15.889796Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mxwpyr3adj2b", "record": "CVE-2026-103936", "field": "creation_timestamp", "uuid": "538e9570-1096-4975-aa3f-e1ba50fc51d1", "content": "\ud83d\udfe0 CVE-2026-103936 - High (7.5)\n\nlibp2p is a JavaScript implementation of the libp2p networking stack.
