{"cve":"CVE-2026-110530","nvd":{"published":"2026-10-31T09:16:32.933","modified":"2026-10-31T09:16:32.933","status":"Received","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/feedwordpress/","https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1196","https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1726","https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L395","https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.1016/syndicatedpost.class.php"],"products":[],"source":"nvd","synced_at":"2026-10-31T09:39:03.416545639+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
