The plugin's SyndicatedPost::sanitize_content() function only strips the 'target' attribute (the lines that would strip 'style' and 'on[a-z]+' event-handler attributes are commented out), and SyndicatedPost::insert_post() deliberately removes WordPress's wp_filter_kses and wp_filter_post_kses filters from content_save_pre before persisting imported feed items via wp_insert_post(). This makes it possible for unauthenticated attackers who control an external feed that a site has already subscribed to to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}],"title":"FeedWordPress <= 2026.0517 - Unauthenticated Stored Cross-Site Scripting via Syndicated Feed Content","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cad2334c-21f5-40bc-8b08-32c12ce1e077?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1726"},{"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1196"},{"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L395"},{"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/"},{"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.1016/syndicatedpost.class.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","baseScore":7.2,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Adrien Brunner"}],"timeline":[{"time":"2026-10-14T16:28:56.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T20:11:36.000Z","lang":"en","value":"Disclosed"}]}}}
