{"id":"CVE-2026-116535","published":"2026-10-31T08:16:48.757","lastModified":"2026-10-31T08:16:48.757","description":"The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 10.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by any Subscriber who sets their display_name to a string containing the literal %%archive_title%% token alongside HTML event-handler payloads, as WordPress stores display names without HTML filtering and the plugin substitutes the token after escaping has already occurred.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.svn.wordpress.org/wp-seopress/trunk/","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L1104","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L1112","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L533","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L542","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-titles-metas.php#L403","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/variables/dynamic-variables.php#L340","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3772366/wp-seopress/trunk/inc/functions/options-social.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/6651c932-aa60-485b-bb5b-b66d5a8963ae?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
