The toilet flush is coming out of the base because the toilet drain is not going into the drain. If the middle of the toilet and the water outlet is misaligned for a long time, the toilet mouth is not put into the water outlet, which will cause water to flow out from the bottom when flushing, you can open the toilet to observe whether it is misaligned. Install a flange and reinstall the toilet, then run the water to test, if no more water comes out, put glue around the toilet.
