Enable Media Replace < 4.1.9 - Author+ Stored XSS via 'location_dir' Parameter

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the ‘location_dir’ parameter due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
