CVE-2024-28863Public exploitNetwork attack vector

Node.js client crash via unbounded path depth

Published Mar 21, 2024 · Updated Feb 13, 2025

Denial of service in node-tar before 6.2.1 allows remote attackers to crash a Node.js client through a deeply nested tar archive. The Unpack CHECKPATH path accepted archive-entry paths of unbounded depth, so extraction recursively created folders until CPU and heap resources were exhausted. A user or application must extract the attacker-supplied archive; reported effects are resource exhaustion and process crash, not data access or modification.
