GHSA-qww7-89xh-x7m7
XWiki configuration files can be accessed through the webjars API
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-webjars-api☕org.xwiki.platform:xwiki-platform-webjars-api☕org.xwiki.platform:xwiki-platform-webjarsReal-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 get access and read configuration files by using URLs such as http://localhost:8080/xwiki/webjars/wiki%3Axwiki/..%2F..%2F..%2F..%2F..%2FWEB-INF%2Fxwiki.cfg. The trick here is to encode the / which is decoded when parsing the URL segment, but not re-encoded when assembling the file path.
Patches
This has been patched in 17.4.0-rc-1, 16.10.7.
Workarounds
There is no known workaround, other than upgrading 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-webjars-api. 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-webjars-api to 16.10.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qww7-89xh-x7m7 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-qww7-89xh-x7m7 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-qww7-89xh-x7m7. 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-qww7-89xh-x7m7 in your dependencies?
O3 detects GHSA-qww7-89xh-x7m7 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
