Description
WordPress Plugin Leaflet Maps Marker (Google Maps, OpenStreetMap, Bing Maps) is prone to multiple vulnerabilities, including cross-site scripting and SQL injection vulnerabilities because it fails to properly sanitize user-supplied input. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, to steal cookie-based authentication credentials, to compromise the application, access or modify data or to exploit vulnerabilities in the underlying database. WordPress Plugin Leaflet Maps Marker (Google Maps, OpenStreetMap, Bing Maps) version 2.3 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.4 or latest
