GHSA-h6gj-6jjq-h8g9 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in org.webjars.npm:jquery-ui. 1 public exploit reference exists, so weaponization risk is real. A fix is available for org.webjars.npm:jquery-ui — see the affected versions and patch details below.
jQuery UI vulnerable to XSS when refreshing a checkboxradio with an HTML-like initial text label
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-h6gj-6jjq-h8g9 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
jquery-uinpmDescription
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>

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.webjars.npm:jquery-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.webjars.npm:jquery-ui to 1.13.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h6gj-6jjq-h8g9 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-h6gj-6jjq-h8g9 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-h6gj-6jjq-h8g9. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Frequently Asked Questions
Is GHSA-h6gj-6jjq-h8g9 in your dependencies?
O3 Security finds GHSA-h6gj-6jjq-h8g9 across Maven, npm, NuGet dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
