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 1.7%, percentile 77: FIRST’s model estimates a 1.7% chance of exploitation activity in the next 30 days, higher than 77% 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-webjars-api (Maven) >= 7.1.4, < 16.10.7, fixed in 16.10.7; org.xwiki.platform:xwiki-platform-webjars-api (Maven) >= 17.0.0-rc-1, < 17.4.0-rc-1, fixed in 17.4.0-rc-1; org.xwiki.platform:xwiki-platform-webjars (Maven) >= 6.1-miletone-2, <= 7.1.3, no fixed version listed. 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 6.1-milestone-2 through 16.10.6, configuration files are accessible through the webjars API. This is fixed in version 16.10.7.

From the GitHub advisory

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.
