GHSA-h6gj-6jjq-h8g9 jQuery UI vulnerable to XSS when refreshing a checkboxradio with an HTML-like initial text label

Impact 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: ```html &lt;img src=x onerror="alert(1)"&gt; ``` and calling: ```js $( "#test-input" ).checkboxradio(); $( "#test-input" ).checkboxradio( "refresh" ); ``` will turn the initial HTML into: ```html ``` and the alert will get executed. Patches The bug has been patched in jQuery UI 1.13.2. Workarounds 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`: ```html &lt;img src=x onerror="alert(1)"&gt; ``` References https://blog.jqueryui.com/2022/07/jquery-ui-1-13-2-released/ For more information If you have any questions or comments about this advisory, search for a relevant issue in the jQuery UI repo.
