Workarounds

If you cannot use the security plugin, add the following config to your .htaccess file

<IfModule mod_headers.c>
    <FilesMatch "\.(?i:svg)$">
        Header set Content-Security-Policy "script-src 'none'"
    </FilesMatch>
</IfModule>

If you are using nginx as server config, you can add the following to your configuration:

server {
    # ...

    location ~* ^.+\.svg$ {
        add_header Content-Security-Policy "script-src 'none'";
    }
}
