GHSA-f93p-f762-vr53 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in org.apache.cxf:apache-cxf. 5 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-f93p-f762-vr53 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Reflected Cross-Site Scripting in Apache CXF
Real-World Exposure
org.apache.cxf:apache-cxf☕org.apache.cxf:apache-cxf☕org.apache.cxf:cxf☕org.apache.cxf:cxfReal-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
By default, Apache CXF creates a /services page containing a listing of the available endpoint names and addresses. This webpage is vulnerable to a reflected Cross-Site Scripting (XSS) attack, which allows a malicious actor to inject javascript into the web page. Please note that the attack exploits a feature which is not typically not present in modern browsers, who remove dot segments before sending the request. However, Mobile applications may be vulnerable.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.cxf:apache-cxf. 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.apache.cxf:apache-cxf to 3.2.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f93p-f762-vr53 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-f93p-f762-vr53 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-f93p-f762-vr53. 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-f93p-f762-vr53 in your dependencies?
O3 detects GHSA-f93p-f762-vr53 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
