No affected components available
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 onerror='doEvilThing()' 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.
