Name of the Vulnerable Software and Affected Versions Leaflet Maps Marker plugin for WordPress versions up to, and including, 3.12.8

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes, such as mapwidthunit, in the plugin's mapsmarker shortcode. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 3.12.8, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the mapsmarker shortcode for users with contributor-level access and above to minimize the risk of exploitation.
