GHSA-p5f8-qf24-24cj is a high-severity (CVSS 8.3) CWE-863 vulnerability in org.xwiki.platform:xwiki-platform-index-tree-macro. 2 public exploit references exist, so weaponization risk is real. A fix is available for org.xwiki.platform:xwiki-platform-index-tree-macro — see the affected versions and patch details below.
Velocity execution without script right through tree macro
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.
How urgent is this, really
GHSA-p5f8-qf24-24cj plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,567 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

Description
Impact
It's possible to execute a Velocity script without script right through the document tree.
To reproduce:
- As a user without script right, create a document, e.g., named Nasty Title
- Set the document's title to
$request.requestURI - Click "Save & View"
- Reload the page in the browser
The navigation panel displays a document named with the current URL, showing that the Velocity code has been executed even though the user doesn't have script right.
Patches
This has been patched in XWiki 14.10.7 and 15.2RC1.
Workarounds
A possible workaround is to:
- modify the page XWiki.DocumentTreeMacros
- search for the code
#set ($discard = $translatedDocument.setTitle($translatedDocument.title)) - modify it into
#set ($discard = $translatedDocument.setcomment(''))

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-index-tree-macro, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-index-tree-macro to 14.10.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p5f8-qf24-24cj 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-p5f8-qf24-24cj can be triaged on real exposure rather than presence alone.
Tailored to GHSA-p5f8-qf24-24cj. 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-p5f8-qf24-24cj in your dependencies?
O3 Security finds GHSA-p5f8-qf24-24cj across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
