XSS in `*Text` options of the Datepicker widget in jquery-ui

### Impact Accepting the value of various `*Text` options of the Datepicker widget from untrusted sources may execute untrusted code. For example, initializing the datepicker in the following way: ```js $( "#datepicker" ).datepicker( { showButtonPanel: true, showOn: "both", closeText: "<script>doEvilThing( 'closeText XSS' )</script>", currentText: "<script>doEvilThing( 'currentText XSS' )</script>", prevText: "<script>doEvilThing( 'prevText XSS' )</script>", nextText: "<script>doEvilThing( 'nextText XSS' )</script>", buttonText: "<script>doEvilThing( 'buttonText XSS' )</script>", appendText: "<script>doEvilThing( 'appendText XSS' )</script>", } ); ``` will call `doEvilThing` with 6 different parameters coming from all `*Text` options. ### Patches The issue is fixed in jQuery UI 1.13.0. The values passed to various `*Text` options are now always treated as pure text, not HTML. ### Workarounds A workaround is to not accept the value of the `*Text` options 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).
