Summary

The SEOPress WordPress plugin (an SEO and AI SEO tool used on WordPress sites) is affected in all versions up to and including 10.3. An authenticated user with even basic subscriber access can insert malicious scripts through their profile display name, which then run in the browsers of visitors or administrators who view affected pages.

Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Read the original 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.
