Summary
The OSM – OpenStreetMap plugin for WordPress up to version 6.1.15 is vulnerable to Stored Cross-Site Scripting via the 'marker_name' and 'file_color_list' shortcode attributes of the [osm_map_v3] shortcode. Insufficient input sanitization and output escaping allow authenticated attackers with Contributor-level access or higher to inject arbitrary scripts that execute when a user visits the page.
Risk Assessment
The risk includes injection of malicious JavaScript that can steal session data, redirect users, or modify page content.
Recommendation
Update the OSM – OpenStreetMap plugin to the latest version and restrict user privileges to the minimum necessary.

Original NVD description (English source)
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.
