This vulnerability can have critical impacts including allowing attackers to execute remote code on your server, perform SQL injection attacks, traverse file paths to access sensitive files, cause denial of service, and potentially other harmful actions.

Because the vulnerability can be exploited by unauthenticated attackers, it poses a significant risk to the security and availability of your website.
