That's it change log says:
This maintenance release fixes and severe bug in 4.9.3, which will cause sites that support automatic background updates to fail to update automatically, and will require action from you (or your host) for it to be updated to 4.9.4.
Of course, as with any updates, you'll need to upgrade immediately, either by downloading it application from the official website, or from your admin panel in automatic mode.
Before proceeding with the upgrade, it would be a good idea to get a full backup.
