What is CVE-2026-55498?
CVE-2026-55498 is a medium-severity path traversal vulnerability in error311 FileRise, published on 14 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-59
