Descriptions

The All in One SEO WordPress plugin before 4.6.1.1 does not validate and escape some of its Post fields before outputting them back, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

El complemento de WordPress All in One SEO anterior a 4.6.1.1 no valida ni escapa algunos de sus campos de publicación antes de devolverlos, lo que podría permitir a los usuarios con el rol de colaborador y superiores realizar ataques de Cross Site Scripting Almacenado.

The All in One SEO – Best WordPress SEO Plugin – Easily Improve SEO Rankings & Increase Traffic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the meta description in all versions up to, and including, 4.6.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
