{"cve":"CVE-2026-116535","nvd":{"published":"2026-10-31T08:16:48.757","modified":"2026-10-31T08:16:48.757","status":"Received","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.svn.wordpress.org/wp-seopress/trunk/","https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L1104","https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L1112","https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L533","https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L542"],"products":[],"source":"nvd","synced_at":"2026-10-31T08:35:03.478229968+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).
