Find if some of the element's attributes contains specific value

I was thinking if there is a way to find if element's attribute contains a specified value. The attribute is unknown. If I have this HTML:

    <input class="first" type="checkbox" data="THE-VALUE" />
    <input class="second" type="checkbox" />
    <input class="third" type="checkbox" name="THE-VALUE" />

I want to find all the inputs that has attribute with value THE-VALUE (in this case .first and .third). I don't need solution for this case where inputs are 3, but if I have 50 inputs and the attributes containing THE-VALUE are all different. I have tried things like .attr(':contains("THE-VALUE")') and $('input[="THE-VALUE"]'), but by obvious reasons it doesn't work.

So my question is .. is there any way to find that ?

$("input").filter(function() {
    return $.grep(this.attributes, function(arg) {
        return arg.nodeValue === "THE-VALUE";
    }).length > 0;
}).prop("checked", true);

Or as a selector extension:

$.expr[':'].hasattrval = function(e, i, p) {
    return $.grep(e.attributes, function(arg) {
        return arg.nodeValue === p[3];
    }).length;
};

$("input:hasattrval('THE-VALUE')").prop("checked", true);
