jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of the of
option of the .position()
util from untrusted sources may execute untrusted code. 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. A workaround is to not accept the value of the of
option from untrusted sources.
