If that's your own server, please update and patch. Download an IDS (Intrusion Detection Software) to detect intrusions made. Check your logs to see if there's any suspicious activities going on.
If others are hosting the forum for you, contact the host's admins.
If the host's admins aren't willing to do anything, change to another host. It's not worth compromising people's data because of that. Do a backup before moving everything to another host.
