What the vulnerability does
01Description
The WP Store Locator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpsl_address' post meta value in versions up to, and including, 2.2.261 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 and opens an injected map marker info window.
