During the scan, Kayran managed to find the Subresource Integrity (SRI) vulnerability.
Subresource Integrity (SRI) provides a mechanism for checking the integrity of resources hosted by the third parties. It also checks that the resource does not perform any malicious processes.
If you use the site with a third-party DNS service and the DNS service is either hacked or hijacked, it means that your site has also been hacked or hijacked.
To safely use Subresource Integrity make sure you add the Integrity attribute into the script tag with a base64 encoded cryptographic hash value.
