CVE-2022-27909Network attack vector

Authenticated filename disclosure via modified URL parameters

Published May 6, 2022 · Updated Feb 25, 2026

Incorrect access control in jDownloads 3.9.8.2 and earlier allows remote authenticated users to view filenames reserved for other users. The affected frontend request handling accepts attacker-modified URL parameters and returns a reserved file's name without enforcing its user assignment. Registered access is required; the flaw discloses names only, with no reported ability to download the reserved files or alter them.
