Researcher Marc-Alexandre Montpas - Sucuri

Description

The All in One SEO plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the SEO settings for posts in versions up to, and including, 2.1.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with subscriber level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
