How severe is CVE-2023-26480?

CVE-2023-26480 has a CVSS score of 8.9/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-26480?

CVE-2023-26480 affects the following packages: org.xwiki.platform:xwiki-platform-livedata-macro (Maven), org.xwiki.platform:xwiki-platform-livedata-macro (Maven), org.xwiki.platform:xwiki-platform-livedata-macro (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-26480?

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.

How do I detect CVE-2023-26480 in my Maven dependencies?

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.

How do I mitigate CVE-2023-26480 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2023-26480 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-26480, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-26480?

CVE-2023-26480 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 52th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-26480?

CVE-2023-26480 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2023-26480 published, and has it been updated?

CVE-2023-26480 was published on March 2, 2023 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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"
      }
