Summary
The WPeMatico RSS Feed Fetcher plugin for WordPress (versions up to and including 2.9) is vulnerable to Stored Cross-Site Scripting because it removes the wp_filter_post_kses filter before saving RSS feed content. An unauthenticated attacker who publishes or compromises an RSS feed subscribed to by an administrator can inject arbitrary scripts into imported posts.
Risk Assessment
An unauthenticated attacker can inject malicious scripts into RSS-imported content, which execute in the browsers of users, including administrators.
Recommendation
Update the WPeMatico plugin to a version newer than 2.9 and verify the trustworthiness of subscribed RSS feeds.

Original NVD description (English source)
The WPeMatico RSS Feed Fetcher plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.9 This is due to the plugin removing WordPress's wp_filter_post_kses filter from content_save_pre immediately before calling wp_insert_post() with RSS feed content, whenever the campaign's last editor had the unfiltered_html capability — a flag the plugin sets automatically for every admin-saved campaign. Imported item content is taken raw from $item->get_content(), only entity-decoded, and stored verbatim in post_content. This makes it possible for unauthenticated attackers, who publish or compromise an RSS feed that an administrator has subscribed a WPeMatico campaign to, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected imported post.
