XSS in the `altField` option of the Datepicker widget in jquery-ui

Details

### Impact Accepting the value of the `altField` option of the Datepicker widget from untrusted sources may execute untrusted code. For example, initializing the datepicker in the following way: ```js $( "#datepicker" ).datepicker( { altField: "<img onerror='doEvilThing()' src='/404' />", } ); ``` will call the `doEvilThing` function.

### Patches The issue is fixed in jQuery UI 1.13.0. Any string value passed to the `altField` option is now treated as a CSS selector.

### Workarounds A workaround is to not accept the value of the `altField` option from untrusted sources.

### For more information If you have any questions or comments about this advisory, search for a relevant issue in [the jQuery UI repo](https://github.com/jquery/jquery-ui/issues). If you don't find an answer, open a new issue.
