</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

mvn dependency:tree -Dincludes=org.xwiki.platform

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-26480, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.xwiki.platform

Analyze the terminal output to locate any version of Xwiki platform livedata macro in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.10), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.xwiki.platform command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Xwiki platform livedata macro, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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. ### Workarounds No known workaround. ### References https://jira.xwiki.org/browse/XWIKI-20143 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](http://jira.xwiki.org/) * Email us at [Security ML](mailto:security@xwiki.org)
