Attention WordPress website owners: a critical security issue has been unearthed in the widely utilized All-in-One SEO plugin. Identified as CVE-2024-3368, this vulnerability presents a significant risk, enabling malicious actors to exploit Stored Cross-Site Scripting (XSS) attacks, potentially compromising all websites using All in One SEO.
It's quite a significant number at the moment, considering that, according to the plugin's
official page, it has more than 3 million active installations.
This vulnerability was not stumbled upon by chance; it was uncovered during routine security assessments conducted by our team. It allows unauthorized contributors to inject JavaScript code into a WordPress post. While this may seem innocuous, it grants unauthorized access to administrative privileges, leaving websites vulnerable to exploitation.
To better understand Stored XSS attacks, picture this: it's like someone slipping a coded note into your website's pocket. Later, when that information is displayed on a webpage without scrutiny, the hidden code springs into action, causing havoc.
Exploiting this vulnerability in All in One SEO is disturbingly straightforward. Bad actors can craft a post containing malicious JavaScript code and insert it into the SEO section. Upon interaction with this compromised content by administrators or other users, the malicious script executes, potentially resulting in the creation of admin accounts or other nefarious activities.
