This makes it possible for authenticated attackers, with subscriber-level permissions and above, to modify the contents of the .htaccess files located in a site's root directory or /wp-content and /wp-includes folders and achieve remote code execution. CVE-2023-46623 appears to be a duplicate of this issue.
