Description
Impact
By creating a document with a specially crafted title, it is possible to trigger remote code execution in the (Solr-based) search in XWiki. This allows any user who can edit the title of a space (all users by default) to execute any Groovy code in the XWiki installation which compromises the confidentiality, integrity and availability of the whole XWiki installation.
To reproduce, as a user without script nor programming rights, create a document with title {{/html}}{{async}}{{groovy}}println("Hello from Groovy Title!"){{/groovy}}{{/async}} and content Test Document. Using the search UI, search for "Test Document", then deploy the Location facet on the right of the screen, next to the search results. The installation is vulnerable if you see an item such as:
Hello from Groovy Title!
</a>
<div class="itemCount">1</div>
</li>
</ul>
{{/html}}
Patches
This has been patched in XWiki 14.10.20, 15.5.4 and 15.10 RC1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-search-solr-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-search-solr-ui to 14.10.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-31984 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
