description

Mapster WP Maps versions through 2.0.5 can store attacker-controlled content that runs as script when a page renders an affected map. An unauthenticated attacker can exploit this when the plugin is active and its map-saving REST endpoint is reachable.

mitigation

Deactivate Mapster WP Maps or restrict unauthenticated access to its map-saving REST endpoint until a vendor-fixed release is available. Review existing map settings and pages using the plugin for unauthorized changes.
