Which packages are affected by GHSA-r279-47wg-chpr?

GHSA-r279-47wg-chpr affects the following packages: org.xwiki.platform:xwiki-platform-administration-ui (Maven), org.xwiki.platform:xwiki-platform-administration-ui (Maven). Ecosystems affected: Maven.

How do I fix GHSA-r279-47wg-chpr?

Update org.xwiki.platform:xwiki-platform-administration-ui to 15.10.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r279-47wg-chpr is resolved across your whole dependency graph.

How do I detect GHSA-r279-47wg-chpr 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-administration-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-r279-47wg-chpr if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is GHSA-r279-47wg-chpr actively exploited in the wild?

No public exploit code has been indexed for GHSA-r279-47wg-chpr yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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&section=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.
