CVE-2026-64856
lowFileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations.
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.20.0, FileRise /api/file/snippet.php does not apply the standard authenticated-session guard before processing short text preview requests. The endpoint still performs FileRise ACL checks, so normal installations do not expose an unauthenticated arbitrary file read, but unauthenticated requests can reach ACL evaluation instead of receiving an immediate 401 response. Only additional unusual proxy-header or ACL misconfiguration is documented as allowing requests to proceed into path and file-content handling. This issue is fixed in version 3.20.0.
