CVE-2022-31160
ADVISORY - githubSummary
Impact
Initializing a checkboxradio widget on an input enclosed within a label makes that parent label contents considered as the input label. If you call .checkboxradio( "refresh" ) on such a widget and the initial HTML contained encoded HTML entities, they will erroneously get decoded. This can lead to potentially executing JavaScript code.
For example, starting with the following initial secure HTML:
<label>
<input id="test-input">
<img src=x onerror="alert(1)">
</label>
and calling:
$( "#test-input" ).checkboxradio();
$( "#test-input" ).checkboxradio( "refresh" );
will turn the initial HTML into:
<label>
<!-- some jQuery UI elements -->
<input id="test-input">
<img src=x onerror="alert(1)">
</label>
and the alert will get executed.
Patches
The bug has been patched in jQuery UI 1.13.2.
Workarounds
To remediate the issue, if you can change the initial HTML, you can wrap all the non-input contents of the label in a span:
<label>
<input id="test-input">
<span><img src=x onerror="alert(1)"></span>
</label>

CVSS:3 Severity and metrics
The CVSS metrics represent different qualitative aspects of a vulnerability that impact the overall score, as defined by the CVSS Specification.
The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone). One example of an Adjacent attack would be an ARP (IPv4) or neighbor discovery (IPv6) flood leading to a denial of service on the local LAN segment (e.g., CVE-2013-6014).
Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.
The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited. For example, a successful exploit may only be possible during the installation of an application by a system administrator.
An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
There is no impact to availability within the impacted component.
