Petition signatures shared Glendale AZ

Our community in Glendale AZ signed a petition for a special meeting to be called regarding the removal of a HOA board member. Those signatures were sent to our property management company certified mail and we are just waiting to hear back from both the management company regarding the findings from the attorney if 37 out of the 48 signatures are valid, however the community just found out that the board member whom the petition is regarding is now calling the people who's signatures are on that petition before they have even been verified as valid voters is calling these homeowners crying to them. This means that the property management company shared these signatures with that board member which have not been verified yet as valid voters. Is this allowed? Does the management company have a right to share these signatures with that board member that the petition is regarding?
