CRITICALRemote code execution from account through SearchAdmin
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The search administration interface doesn't properly escape the id and label of search user interface extensions, allowing the injection of XWiki syntax containing script macros including Groovy macros that allow remote code execution, impacting the confidentiality, integrity and availability of the whole XWiki instance. This attack can be executed by any user who can edit some wiki page like the user's profile (editable by default) as user interface extensions that will be displayed in the search administration can be added on any document by any user.
To reproduce, edit any document with the object editor, add an object of type XWiki.UIExtensionClass, set "Extension Point Id" to org.xwiki.platform.search, set "Extension ID" to {{async}}{{groovy}}services.logging.getLogger("attacker").error("Attack from extension id succeeded!"){{/groovy}}{{/async}}, set "Extension Parameters" to label={{async}}{{groovy}}services.logging.getLogger("attacker").error("Attack from label succeeded!"){{/groovy}}{{/async}} and "Extension Scope" to "Current User". Then open the page XWiki.SearchAdmin, e.g., on http://localhost:8080/xwiki/bin/view/XWiki/SearchAdmin. If there are error log messages in XWiki's log that announce that attacks succeeded, the instance is vulnerable.
Patches
The necessary escaping has been added in XWiki 14.10.15, 15.5.2 and 15.7RC1.
Workarounds
The patch can be manually applied to the page XWiki.SearchAdmin.

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-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.xwiki.platform:xwiki-platform-search-ui to 14.10.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7654-vfh6-rw6x is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-7654-vfh6-rw6x is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-7654-vfh6-rw6x. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-7654-vfh6-rw6x in your dependencies?
O3 detects GHSA-7654-vfh6-rw6x across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
