How to Fix CVE-2023-31126
To remediate this vulnerability, upgrade all affected Xwiki commons xml dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.xwiki.commons</groupId>
<artifactId>xwiki-commons-xml</artifactId>
<version>14.10.4</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.xwiki.commonsHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-31126, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.commonsAnalyze the terminal output to locate any version of Xwiki commons xml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.10.4), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.xwiki.commons 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

"details" : "### Impact\nThe HTML sanitizer, introduced in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid data attributes. This can be exploited, e.g., via the link syntax in any content that supports XWiki syntax like comments in XWiki: \n\n```\n[[Link1>>https://XWiki.example.com||data-x/onmouseover=\"alert('XSS1')\"]].\n```\n\nWhen a user moves the mouse over this link, the malicious JavaScript code is executed in the context of the user session. When this user is a privileged user who has programming rights, this allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance.\n\nNote that this vulnerability does not affect restricted cleaning in HTMLCleaner as there attributes are cleaned and thus characters like `/` and `>` are removed in all attribute names.\n\n### Patches\nThis problem has been patched in XWiki 14.10.4 and 15.0 RC1 by making sure that data attributes only contain allowed characters.\n\n### Workarounds\nThere are no known workarounds apart from upgrading to a version including the fix.\n\n### References\n* https://jira.xwiki.org/browse/XCOMMONS-2606\n* https://github.com/xwiki/xwiki-commons/commit/0b8e9c45b7e7457043938f35265b2aa5adc76a68\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Jira XWiki](https://jira.xwiki.org/)\n* Email us at [XWiki Security mailing-list](mailto:security@xwiki.org)",
