Summary
The All in One SEO Pack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple parameters in versions up to, and including, 4.2.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with Contributor+ role to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
