Summary
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.
