FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.18.0, FileRise flattens logical folder paths into metadata filenames by replacing separators and spaces with hyphens, so distinct folders such as team/docs and team-docs can share one metadata file. Because uploader metadata is used to authorize read_own and ownership-restricted edits, a low-privileged user who controls one colliding folder, knows the target basename, and already has read_own access to the target folder can alter the metadata used by that folder, make the victim file appear attacker-owned, read it, and modify it when edit-own permission is also available.
This issue is fixed in version 3.18.0.
