CVE-2022-45475Public exploitNetwork attack vector

Unauthenticated file disclosure via missing access checks

Published Nov 25, 2022 · Updated Apr 29, 2025

Improper access control in Tiny File Manager 2.4.8 allows remote attackers to read internal files through its web interface. The web-access path serves uploaded files without checking whether the requester has an authenticated application session. In the published exploit chain, an administrator must first be induced to upload a chosen file; this flaw then exposes that file without authentication.
