How to Fix CVE-2023-29206
To remediate this vulnerability, upgrade all affected Xwiki platform skin skinx 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.platform</groupId>
<artifactId>xwiki-platform-skin-skinx</artifactId>
<version>14.9-rc-1</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.platformHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-29206, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.platformAnalyze the terminal output to locate any version of Xwiki platform skin skinx in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.9-rc-1), 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.

"details" : "### Impact\n\nThere was no check in the author of a JavaScript xobject or StyleSheet xobject added in a XWiki document, so until now it was possible for a user having only Edit Right to create such object and to craft a script allowing to perform some operations when executing by a user with appropriate rights. \n\n### Patches\n\nThis has been patched in XWiki 14.9-rc-1 by only executing the script if the author of it has Script right. \n\n### Workarounds\n\nThe only known workaround consists in applying [the following patch](https://github.com/xwiki/xwiki-platform/commit/fe65bc35d5672dd2505b7ac4ec42aec57d500fbb) and rebuilding and redeploying `xwiki-platform-skin-skinx`.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Jira](http://jira.xwiki.org)\n* Email us at [Security ML](mailto:security@xwiki.org)\n",
