CVE-2026-82460Public exploitNetwork attack vectorHinoki check available

Arbitrary file access via unchecked normalized paths

Published Aug 29, 2026 · Updated Aug 29, 2026

Path traversal in Cloud Commander before 19.20.2 allows remote attackers to read or alter files outside a configured root. The REST move, copy, rename, pack, and extract handlers normalize user paths without enforcing containment, while the markdown relative-path branch reads the joined path directly. Exploitation is unauthenticated when optional authorization is disabled, and the server process's filesystem permissions bound which files are exposed.
