Description Guilherme de Almeida Suckevicz 2021-11-01 17:24:31 UTC
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.

Affects: fedora-all [bug 2019156]

Comment 3 Garrett Tucker 2021-11-11 20:26:52 UTC
After review, RHEL is unaffected as there is no instance of pcs using the affected widget. While pcs does make use of jequery-ui, it is limited in usage and scope and there is no use of the 'of' field in the position util used.
