XWiki Platform is a generic wiki platform. Starting in version 2.3 and prior to versions 15.10.9, 16.3.0, any user with script rights can perform arbitrary remote code execution by adding instances of `XWiki.ConfigurableClass` to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This has been patched in XWiki 15.10.9 and 16.3.0. No known workarounds are available except upgrading.

GHSA-r279-47wg-chpr — XWiki allows RCE from script right in configurable sections

2026-10-04T04:51:34.423271+00:00

Affected: Maven: org.xwiki.platform:xwiki-platform-administration-ui

### Impact Any user with script rights can perform arbitrary remote code execution by adding instances of `XWiki.ConfigurableClass` to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation.

To reproduce on a instance, as a user with script rights, edit your user profile and add an object of type `XWiki.ConfigurableClass` ("Custom configurable sections"). Set "Display in section" and "Display in category" to `other`, "Scope" to `Wiki and all spaces` and "Heading" to: ``` #set($codeToExecute = 'Test') #set($codeToExecuteResult = '{{async}}{{groovy}}services.logging.getLogger("attacker").error("Attack from Heading succeeded!"){{/groovy}}{{/async}}') ``` Save the page and view it, then add `?sheet=XWiki.AdminSheet&viewer=content§ion=other` to the URL. If the logs contain "attacker - Attack from Heading succeeded!", then the instance is vulnerable.

### Patches This has been patched in XWiki 15.10.9 and 16.3.0.

### Workarounds We're not aware of any workaround except upgrading.
