CVE-2026-101357

The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'seopress_google_analytics_matomo_id' parameter in all versions up to, and including, 10.2 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 requires an administrator to have delegated the Analytics management capability to the Subscriber role via the plugin's Advanced > Security settings.
