CVE-2026-55498 Details
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.
A symlink escape vulnerability has been identified in FileRise, a self-hosted web-based file manager, in version 3.14.0 prior to 3.15.0. The issue arises when public shared-folder links with subfolder browsing enabled allow access to files outside the intended shared folder. This occurs because the shared folder paths resolve symbolic links without enforcing the original shared folder as the real-path boundary. An unauthenticated user with a valid share token can exploit this to access files in sibling directories under the upload root that were not explicitly shared.
Users can update to FileRise version 3.15.0, which addresses this vulnerability by enforcing the original shared folder as the real-path boundary for all shared-folder operations, including listing, file downloads, upload targets, and ZIP creations.
