Impact

Accepting the value of the of option of the .position() util from untrusted sources may execute untrusted code. For example, invoking the following code:

$( "#element" ).position( {
	my: "left top",
	at: "right bottom",
	of: "<img src="/404" />",
	collision: "none"
} );

will call the doEvilThing() function.

Patches

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

Workarounds

A workaround is to not accept the value of the of option from untrusted sources.
