CVE-2026-33005Network attack vector

Authenticated metadata disclosure via unchecked folder IDs

Published Apr 9, 2026 · Updated Apr 9, 2026

Improper privilege handling in Apache OpenMeetings 3.1.0 through 8.x allows remote authenticated users to read folder and file metadata. FileWebService accepts an arbitrary folder identifier without verifying that the authenticated user may access that folder, then returns FileItemDTO records for its files and subfolders. Any registered account can enumerate identifiers, types, names, and other metadata across folders, but the flaw does not expose file contents.
