What the vulnerability does
The Image Photo Gallery Final Tiles Grid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Custom scripts' setting in all versions up to, and including, 3.6.8 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.

An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, potentially compromising their sessions or stealing data. The vulnerability affects the entire site scope due to how the plugin processes and displays user input.
