Last Updated February 2, 2023
Researcher Marc-Alexandre Montpas - Sucuri

Description

The All in One SEO plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the aioseop_ajax_save_meta() function in versions up to, and including, 2.1.5. This makes it possible for authenticated attackers with subscriber level permissions and above to modify some of the SEO settings of the plugin for any given post.
