The _validate_url method should prevent any URL that points to a local network (e.g. localhost). The following patch is submitted by a player. Do you think this patch has fixed the security bug?

patch.py

def _validate_url(url: str):
    """Should prevent URLs that point to a local network (e.g. localhost)
    """
    if search("localhost", url) is not None:
        raise Errors.ErrInvalidURL

    if search("/latest/meta-data", url) is not None:
        raise Errors.ErrInvalidURL

    if search("/etc/passwd", url) is not None:
        raise Errors.ErrInvalidURL
        
    if search("/computeMetadata", url) is not None:
        raise Errors.ErrInvalidURL
        
    if search(r"^http[s]?://.*", url) is None:
        raise Errors.ErrInvalidURL

    if search(r"(224.0.0.1|192.168.0.1|169.254.0.255)", url) is not None:
