CVE-2026-46679

Estado: AplazadaAlta (7.5)—

libp2p is a JavaScript Implementation of libp2p networking stack. Prior to version 15.0.23, three cooperating omissions in @libp2p/gossipsub allow an unauthenticated single peer to exhaust the Node.js heap of any gossipsub node with default options. This issue has been patched in version 15.0.23.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
