CVE-2025-32973 — XWiki is a generic wiki platform

Critical CVSS 9

XWiki is a generic wiki platform. In versions starting from 15.9-rc-1 to before 15.10.12, from 16.0.0-rc-1 to before 16.4.3, and from 16.5.0-rc-1 to before 16.8.0-rc-1, when a user with programming rights edits a document in XWiki that was last edited by a user without programming rights and contains an XWiki.ComponentClass, there is no warning that this will grant programming rights to this object. An attacker who created such a malicious object could use this to gain programming rights on the wiki. For this, the attacker needs to have edit rights on at least one page to place this object and then get an admin user to edit that document. This issue has been patched in versions 15.10.12, 16.4.3, and 16.8.0-rc-1.

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.
