Impact
A hard-coded secret was used in the NixOS module for the OnlyOffice document server to protect its file cache. An attacker with knowledge of an existing revision ID could use this secret to obtain a document.
In practice, an arbitrary revision ID should be hard to obtain. The primary impact is likely the access to known documents from users with expired access.
Resolution
Pass your own security nonce file.
