GHSA-mxf2-4r22-5hq9
HIGHXWiki Platform Web Parent POM vulnerable to XSS in the attachment history
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.
Blast Radius
org.xwiki.platform:xwiki-platform-web☕org.xwiki.platform:xwiki-platform-webReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
It's possible to store a JavaScript which will be executed by anyone viewing the history of an attachment containing javascript in its name.
For example, attachment a file with name ><img src=1 onerror=alert(1)>.jpg will execute the alert.
Patches
This issue has been patched in XWiki 13.10.6 and 14.3RC1.
Workarounds
It is possible to replace viewattachrev.vm, the entry point for this attack, by a patched version from the patch without updating XWiki.

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-web. 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-web to 13.10.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mxf2-4r22-5hq9 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-mxf2-4r22-5hq9 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-mxf2-4r22-5hq9. 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-mxf2-4r22-5hq9 in your dependencies?
O3 detects GHSA-mxf2-4r22-5hq9 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
