What it is

Raven 2.0.0 through 3.0.0 contains a missing authorization vulnerability in legacy methods in raven/api/raven_message.py that skip the workspace membership check. Authenticated non-members can call get_messages_with_dates or get_all_files_shared_in_channel with predictable channel IDs to read Public channel history and Open/Public channel file metadata across workspaces.
