Initializing a checkboxradio widget on an input enclosed within a label makes
that parent label contents considered as the input label. If you call
.checkboxradio( "refresh" )
on such a widget and the initial HTML contained
encoded HTML entities, they will erroneously get decoded. This can lead to
potentially executing JavaScript code.
For example, starting with the following initial secure HTML:
<label>
<input id="test-input">
<img src=x onerror="alert(1)">
</label>
and calling:
$( "#test-input" ).checkboxradio();
$( "#test-input" ).checkboxradio( "refresh" );
will turn the initial HTML into:
<label>
<input id="test-input">
<img src>
</label>
and the alert will get executed.
The bug has been patched in jQuery UI 1.13.2.
To remediate the issue, if you can change the initial HTML, you can wrap all
the non-input contents of the label
in a span
:
<label>
<input id="test-input">
<span><img src=x onerror="alert(1)"></span>
</label>
