The rear screws look good. They are the ones you need to be the most concerned with. If they fit properly, hold properly, you’re good to go.
I believe someone replaced the two front screws, for whatever reason, with what look to be drywall screws. Could be wrong, but they certainly look incorrect for that application, but they are probably doing the job of holding the bridge down, preventing front lift.
To fix it, if you ever get the urge to, all you have to do is get some toothpicks, wood glue, and the proper screws. Fill the holes with a bit of wood glue, insert a toothpick, let it dry completely, pilot hole it with a slightly smaller diameter than the new screw shaft, insert new screws. Takes very little time (minus the dry time wait). Or, you may just be able to find more proper screws, put them in, call it a day. Or, you can just leave it be.
