CVE-2022-31160 jQuery UI contains potential XSS vulnerability when refreshing a checkboxradio with an HTML-like initial text label

What is CVE-2022-31160?

CVE-2022-31160 is a medium-severity cross-site scripting vulnerability in Debian Debian Linux, published on 20 Jul 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

jQuery UI is a curated set of user interface interactions, effects, widgets, and themes built on top of jQuery. Versions prior to 1.13.2 are potentially vulnerable to cross-site scripting. Initializing a checkboxradio widget on an input enclosed within a label makes that parent label contents considered as the input label. Calling `.checkboxradio( "refresh" )` on such a widget and the initial HTML contained encoded HTML entities will make them erroneously get decoded. This can lead to potentially executing JavaScript code. The bug has been patched in jQuery UI 1.13.2. To remediate the issue, someone who can change the initial HTML can wrap all the non-input contents of the `label` in a `span`.

Weakness: CWE-79
