WP Remote Site Search < 1.0.5 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The WP Remote Site Search plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping on the
'max_results' user supplied attribute. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
