Description

FileRise is a self-hosted web file manager / WebDAV server. Prior to version 3.10.0, a broken access control issue in FileRise's ONLYOFFICE integration allows an authenticated user with read-only access to obtain a signed save callbackUrl for a file and then directly forge the ONLYOFFICE save callback to overwrite that file with attacker-controlled content. This issue has been patched in version 3.10.0.
