Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-4xm7-5q79-3fch.
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-4xm7-5q79-3fch 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 377,166 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
org.xwiki.platform:xwiki-platform-appwithinminutes-ui☕org.xwiki.platform:xwiki-platform-appwithinminutes-uiReal-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
Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the DeleteApplication page to perform a XSS, e.g. by using URL such as:
xwiki/bin/view/AppWithinMinutes/DeleteApplication?appName=Menu&resolve=true&xredirect=javascript:alert(document.domain)
This vulnerability exists since XWiki 6.2-milestone-1.
Patches
The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1.
Workarounds
It's possible to workaround the vulnerability by editing the page AppWithinMinutes.DeleteApplication to perform checks on it, but note that the appropriate fix involves new APIs that have been recently introduced in XWiki. See the referenced jira tickets.

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-appwithinminutes-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-appwithinminutes-ui to 14.10.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4xm7-5q79-3fch 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-4xm7-5q79-3fch can be triaged on real exposure rather than presence alone.
Tailored to GHSA-4xm7-5q79-3fch. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
