All in One SEO Forced Update due to Severe Security Issue

Dec 22, 2021 Hristo Pandjarov

A serious security issue was found in All In One SEO Plugin, affecting all versions between 4.0.0 and 4.1.5.2. The vulnerability is of the Privilege Escalation type, meaning that authenticated users with minimal rights can execute actions that are above their access level.

Due to the type of the exploit and its severity, we have decided to forcefully update all affected versions of this plugin hosted on SiteGround servers to 4.1.5.3 which fixes the problem. We do not expect any negative effects on the plugin functionality or your site performance. However, don’t hesitate to contact our support team if you notice an issue that might be related to this update.
