{"affected":[],"cveId":"CVE-2026-110530","cwes":["CWE-79"],"description":"The FeedWordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2026.0517 via syndicated RSS/Atom feed content. 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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.2,"severity":"high","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793557027577,"publishedAt":1793438192933,"references":[{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1196"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1726"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L395"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.1016/syndicatedpost.class.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cad2334c-21f5-40bc-8b08-32c12ce1e077?source=cve"}],"remediation":[],"revision":"f5f066e6e4ab12f4b2dfec494da50f69eafbf115abea8d47166020422e2d04c4","sources":[{"modifiedAt":1793557027577,"name":"NVD","retrievedAt":1793578556635,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110530"}],"ssvc":{"assessedAt":1793554441156,"automatable":"no","exploitation":"none","source":"NVD SSVC: 134c704f-9b21-4f2e-91b3-4a467353bcc0","technicalImpact":"partial"},"status":"published","title":"CVE-2026-110530","updatedAt":1793578556635}
