CVE-2026-41680 Apr 24, 17:26 npm HIGH POC PATCH GHSA This Week

Unauthenticated remote attackers can crash Node.js applications using marked versions 18.0.0-18.0.1 by sending a specially crafted 3-byte sequence (tab, vertical tab, newline). The infinite recursion loop exhausts memory and triggers an out-of-memory crash, enabling complete denial of service against any exposed markdown parsing endpoint. Vendor-released patch fixes the vulnerability in version 18.0.2. No public exploit identified at time of analysis, though the attack input is trivially simple and reproducible. CVSS v4.0 8.7 reflects high availability impact with network reachability and no authentication barriers.
