Description
The OSM – OpenStreetMap plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'marker_name' and 'file_color_list' shortcode attribute of the [osm_map_v3] shortcode in all versions up to and including 6.1.15. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
