Vulnerability Details : CVE-2023-6971
The Backup Migration plugin for WordPress is vulnerable to Remote File Inclusion in versions 1.0.8 to 1.3.9 via the 'content-dir' HTTP header. This makes it possible for unauthenticated attackers to include remote files on the server, resulting in code execution. NOTE: Successful exploitation of this vulnerability requires that the target server's php.ini is configured with 'allow_url_include' set to 'on'. This feature is deprecated as of PHP 7.4 and is disabled by default, but can still be explicitly enabled in later versions of PHP.
