Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.8%, percentile 78: FIRST’s model estimates a 1.8% chance of exploitation activity in the next 30 days, higher than 78% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
org.xwiki.platform:xwiki-platform-skin-skinx(Maven) >= 4.2-milestone-2, < 16.10.7, fixed in 16.10.7. Check your lockfile, including transitive dependencies.
What it is
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 4.2-milestone-2 through 16.10.6, configuration files are accessible through jsx and sx endpoints. It's possible to access and read configuration files by using URLs such as http://localhost:8080/bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false. This is fixed in version 16.10.7.
