Short explanation

The WPeMatico RSS Feed Fetcher plugin for WordPress up to version 2.9 contains a Stored Cross-Site Scripting vulnerability that allows unauthenticated attackers to exploit RSS feed content imports.

Why does it matter?

This flaw enables unauthenticated attackers to inject malicious web scripts that execute whenever a user accesses an impacted imported post.

What should be done?

  • Follow vendor advisories and security updates
  • Monitor plugin release notes and status
  • Apply official vendor patches when available
Chain of evidence and sources2 verified claims

WPeMatico RSS Feed Fetcher eklentisi 2.9 ve önceki sürümlerinde Saklı Siteler Arası Betik Çalıştırma zafiyetine açıktır.

Zafiyet, wp_filter_post_kses filtresinin kaldırılması ve ham RSS içeriğinin kaydedilmesi sonucunda oluşur.

Show the technical text from the sources

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.
