CVE-2026-55498
FileRise Shared Folder Symlink Escape
Description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.15.0, FileRise public shared-folder links with subfolder browsing enabled can follow a symbolic link inside the shared folder to a sibling directory under the upload root. An unauthenticated holder of a valid share token can use shared-folder listing, direct download, or ZIP creation to access files outside the folder that was actually shared. The flaw occurs because the affected shared-folder paths resolve symlinks without enforcing the original shared folder as the real-path boundary. This issue is fixed in version 3.15.0.
