Real-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. AbstractSxExportURLFactoryActionHandler#processSx does not escape anything from SSX document reference when serializing it on filesystem, so it's easy to mess up the HTML export process with reference elements containing filesystem syntax like "../", "./". or "/" in general (the last two not causing any security threat, but can cause conflicts with others serialized files). Patch can be found in 13.6-rc-1. Giving script or subwiki admin right only to trusted people and disabling HTML/PDF export can be done as workaround.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-skin-skinx, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. 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.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
