Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache OpenMeetings versions from 3.10 before 9.0.0 are affected. A registered user with valid credentials can query a web service to list files and sub-folders of any folder by ID, exposing metadata such as id, type and name, though not file contents. Users should upgrade to version 9.0.0, which fixes the issue.
