Recommendation: Plan a near-term fix — a public PoC already exists.

openmediavault before 4.1.36 and 5.x before 5.5.12 allows authenticated PHP code injection attacks, via the sortfield POST parameter of rpc.php, because json_encode_safe is not used in config/databasebackend.inc. Successful exploitation allows arbitrary command execution on the underlying operating system as root.
