NVD description
The Rank Math SEO – AI SEO Tools to Dominate SEO Rankings plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0.276 via deserialization of untrusted input in the updateMeta REST API endpoint. This makes it possible forauthenticated attackers, with Contributor-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to achieve remote code execution by writing a webshell to the uploads directory.
