{"id":"CVE-2026-110252","published":"2026-10-16T07:17:11.030","lastModified":"2026-10-16T15:17:10.490","description":"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.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/etruel/wpematico/commit/44c4894a0ad92a711c534ad4d822c0b5d7c3dffe","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/campaign_fetch.php#L400","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/campaign_fetch.php#L773","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/campaign_fetch.php#L777","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/wpematico_functions.php#L3226","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/wpematico_functions.php#L3326","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3747465/wpematico/trunk/includes/campaign_fetch.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e87fc1bf-af05-4089-a164-8a2e73c68e8c?source=cve","tags":[]}],"exploitRefs":[{"url":"https://github.com/etruel/wpematico/commit/44c4894a0ad92a711c534ad4d822c0b5d7c3dffe","tags":[]}],"hasPoc":true,"ai":null}
