GHSA-h7cw-44vp-jq7h
HIGHGHSA-h7cw-44vp-jq7h is a high-severity (CVSS 8.8) CWE-863 vulnerability in org.xwiki.platform:xwiki-platform-help-ui. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-h7cw-44vp-jq7h is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
XWiki Platform vulnerable to privilege escalation (PR) from account through TipsPanel

Description
Impact
It's possible to execute any wiki content with the right of the TipsPanel author by creating a tip UI extension.
To reproduce:
- Add an object of type UIExtensionClass
- Set "Extension Point ID" to org.xwiki.platform.help.tipsPanel
- Set "Extension ID" to org.xwiki.platform.user.test (needs to be unique but otherwise doesn't matter)
- Set "Extension Parameters" to
tip={{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}} - Set "Extension Scope" to "Current User".
- Click "Save & View"
- Open the "Help.TipsPanel" document at <xwiki-host>/xwiki/bin/view/Help/TipsPanel where <xwiki-host> is the URL of your XWiki installation and press refresh repeatedly.
The groovy macro is executed, after the fix you get an error instead.
Patches
This has been patched in XWiki 15.1-rc-1 and 14.10.5.
Workarounds

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-help-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-help-ui to 14.10.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h7cw-44vp-jq7h 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-h7cw-44vp-jq7h 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-h7cw-44vp-jq7h. 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-h7cw-44vp-jq7h in your dependencies?
O3 detects GHSA-h7cw-44vp-jq7h across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
