CVE-2026-96564

The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Author Display Name in all versions up to, and including, 10.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the 'Track Authors' custom dimension to be configured in the plugin's Google Analytics 4 or Matomo settings, and the attacker must be able to publish public singular content (e.g., via bbPress forum topics) so that the injected display name is rendered in the tracking script.
