CVE-2026-44224 Details
Description
Wiki.js is an open source wiki app built on Node.js. Prior to 2.5.313, the users.update GraphQL mutation accepts an arbitrary groups array and applies it directly to the database with no validation of the group IDs supplied. The resolver passes the caller's arguments straight to the model without any ownership check or restriction on which groups can be assigned. A user with manage:users — a permission typically delegated to wiki moderators for account management — can set groups:[1] on their own account to self-assign to the Administrators group. After re-authentication, the fresh JWT carries manage:system, granting full site administrator access in a single mutation call. This vulnerability is fixed in 2.5.313.
A critical privilege escalation vulnerability has been identified in Wiki.js versions through 2.5.312. The issue arises in the GraphQL 'users.update' mutation, which accepts an arbitrary array of group IDs and applies them to the database without any validation. This lack of oversight allows users with the 'manage:users' permission, typically assigned to moderators, to self-assign themselves to the Administrators group. After re-authenticating, these users receive a JSON Web Token (JWT) that includes 'manage:system' privileges, granting them full administrative access.
Users are advised to update to Wiki.js version 2.5.313 or later, where this vulnerability has been fixed.
