The executor of a will changed it without permission, what could happen to her?

Generally, only the testator has the authority to make that decision. There would have to be some compelling reason why the testator's wishes would not be honored, assuming the valid execution of the will itself.

The terms of the original Will prevail. Only the grantor can change a Will, no one else.

The change will be ignored. No one other than the creater of the will can change it.

The executor does not have authority to change a Will. This should be brought to the attention of the Court if the Will is probated or used to transfer property. The Court may find her changing of the Will grounds for discharging her. You don't say whether the person making the Will is deceased, or whether there is any property to be probated through the Court. That might help get more complete answers.

Is the creator of the will still alive? A will only takes effect on death. If the person is still alive, then you should have this person create a new will to reflect his or her true intent. If the will creator is an elder, call APS or local law enforcement and report the potential elder abuse. If the person is deceased, then the probate court should surcharge and remove the executor.
