CVE-2026-97360: HFS2 unauthenticated arbitrary file access in template engine

CVE-2026-97360 · Severity: critical · CVSS 10 · Published 2026-09-24

HFS2 is a file sharing service that allows users to access files over a network. Unauthenticated attackers can bypass authorization checks in the template engine to read, write, append, and delete any files that the HFS service account can access on the host system, potentially exposing sensitive data, modifying critical files, or disrupting service availability.

Technologies: Wgetnz HFS2. Vendors: Wgetnz.

Technical details

HFS2 versions 2.4.0 and earlier contain a missing authorization vulnerability (CWE-862) in the macro dispatcher and path resolver components. Unauthenticated network attackers can exploit the lack of authorization model combined with insufficient path validation to manipulate the template engine and access files outside the intended shared folder. The vulnerability enables complete compromise of confidentiality, integrity, and availability on the affected host.
