Name of the Vulnerable Software and Affected Versions Backup Migration plugin for WordPress versions 1.0.8 through 1.3.9

Description The issue allows unauthenticated attackers to include remote files on the server, resulting in code execution, via the content-dir HTTP header. Successful exploitation requires the target server's php.ini to be 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.

Recommendations For versions 1.0.8 through 1.3.9, consider disabling the content-dir HTTP header until a patch is available. Additionally, ensure the allow url include setting in php.ini is set to off to prevent exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
