CVE-2023-26480 is a high-severity (CVSS 8.9) Cross-site Scripting (XSS) vulnerability in org.xwiki.platform:xwiki-platform-livedata-macro. 1 public exploit reference exists, so weaponization risk is real. A fix is available for org.xwiki.platform:xwiki-platform-livedata-macro — see the affected versions and patch details below.
XWiki-Platform vulnerable to stored Cross-site Scripting via the HTML displayer in Live Data
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for CVE-2023-26480.
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
CVE-2023-26480 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.

Description
Impact
A user without script rights can introduce a stored XSS by using the Live Data macro.
For instance:
{{liveData id="movies" properties="title,description"}}
{
"data": {
"count": 1,
"entries": [
{
"title": "Meet John Doe",
"url": "https://www.imdb.com/title/tt0033891/",
"description": "<img onerror='alert(1)' src='foo' />"
}
]
},
"meta": {
"propertyDescriptors": [
{
"id": "title",
"name": "Title",
"visible": true,
"displayer": {"id": "link", "propertyHref": "url"}
},
{
"id": "description",
"name": "Description",
"visible": true,
"displayer": "html"
}
]
}
}
{{/liveData}}
Patches
This has been patched in XWiki 14.9, 14.4.7, and 13.10.10.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-livedata-macro, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-livedata-macro to 13.10.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-26480 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 CVE-2023-26480 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-26480. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-26480 in your dependencies?
O3 Security finds CVE-2023-26480 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
