Real-World Exposure
org.xwiki.platform:xwiki-platform-skin-skinxReal-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
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions AbstractSxExportURLFactoryActionHandler#processSx does not escape anything from SSX document references when serializing it on filesystem, it is possible to for the HTML export process to contain reference elements containing filesystem syntax like "../", "./". or "/" in general. The referenced elements are not properly escaped. This issue has been resolved in version 13.6-rc-1. This issue can be worked around by limiting or disabling document export.

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-skin-skinx. 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-skin-skinx to 13.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-23620 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 CVE-2022-23620 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 CVE-2022-23620. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
