Is there a ready-made CMS for the project of marks (geo pins) on the map?

Question

CMS

Hello. The purpose of this CMS is to create a site where people in the city could mark problem areas (a pipe burst, a light bulb burned out, a garbage dump, etc.) or an emergency site with the same principle. Those. where the priority is the card itself.
Interested in a ready-made solution for installation on a regular shared hosting. install.php.., a couple of minor tweaks and go...
Basically any map background, but better just with the ability to select a layer.
It is also desirable that there be a personal account or another way to track the status of marks on the map by the user.
Tell me if there are ready-made open source solutions or paid options?
