CVE-2024-11620Public exploitNetwork attack vector

Authenticated code execution via unchecked .htaccess overwrite

Published Nov 28, 2024 · Updated May 11, 2026

Code injection in Rank Math SEO 1.0.231 and earlier allows remote authenticated users to execute PHP code through .htaccess changes. The update_htaccess function writes unslashed htaccess_content from a nonce-bearing admin_post request into the site's .htaccess file without an additional capability check. Access to General Settings or Titles & Meta Settings is required; administrators have it by default, and custom roles can receive it.
