just bought a rental property and found that if the bath faucets are turned on high, water starts coming out of the shower head without the diverter on the spout being pulled. new spout has been installed

Sounds like a restriction in the pipe feeding the spout. If it's galvanized, maybe it's rusting up or if it's pex/cpvc, it's too small in diameter. Or, if there was a shower restrictor in the control valve, it's missing or the valve installed upsidedown.

Pipe size is NOT the cause of it. Pipe type may be the reason. But there are several possibilities and would have to be there to diagnose them.

Excessive water pressure can cause this also.

If the hot and cold faucet supply lines have shutoff valves you can close down the shutoffs to a point that water flow is not as high but still adequate. If that stops the water from coming out of the shower head then you know it is caused by too much pressure or volume from the supply lines. You can also add a screw-on chrome shower head shutoff valve inline with the shower arm, keep it shut off unless taking a shower.

Here's one example:
