Description
The Mapster WP Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple fields in versions up to, and including, 1.20.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
