Description
The Inactive Logout plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ina_redirect_page_individual_user' parameter in all versions up to, and including, 3.5.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
