Vulnerability in pluginever Content Pilot – Autoblogging & Affiliate Marketing Suite

[ Description ]Official description

The Content Pilot – Autoblogging & Affiliate Marketing Suite plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.2.4. This is due to the plugin extracting the HTML meta description from each remotely-fetched article (WPCP_Readability::parse_meta()), piping that value through the article template substitution and html_entity_decode() in WPCP_Module::insert_post(), and then calling wp_insert_post() after switching the current user to the configured campaign author (an Administrator with the unfiltered_html capability by default) — so no wp_kses_post sanitization is applied to the attacker-controlled HTML before it is persisted as post_content and rendered on the front end. This makes it possible for unauthenticated attackers who control the content of any RSS source an administrator has configured a Content Pilot RSS campaign to consume to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
