CVE-2022-23621 — XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

Medium CVSS 5.5

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with SCRIPT right can read any file located in the XWiki WAR (for example xwiki.cfg and xwiki.properties) through XWiki#invokeServletAndReturnAsString as `$xwiki.invokeServletAndReturnAsString("/WEB-INF/xwiki.cfg")`. This issue has been patched in XWiki versions 12.10.9, 13.4.3 and 13.7-rc-1. Users are advised to update. The only workaround is to limit SCRIPT right.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
