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:
$( "#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.
