CVE-2026-44224: CWE-269: Improper Privilege Management in requarks wiki
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.
AI Analysis
Technical Summary
Wiki.js, an open source Node.js wiki application, had a privilege management flaw in versions before 2.5.313. The users.update GraphQL mutation accepted an arbitrary groups array and applied it directly to the database without validating the group IDs or checking ownership. A user with manage:users permission could exploit this by assigning themselves to the Administrators group, thereby gaining manage:system permissions and full site administrator access after re-authentication. This vulnerability is classified under CWE-269 (Improper Privilege Management) and has a CVSS 4.0 base score of 8.6, indicating high severity. The issue is resolved in version 2.5.313.
Potential Impact
An attacker with the manage:users permission can escalate their privileges to full site administrator by manipulating group assignments in the users.update mutation. This grants them manage:system permissions, effectively giving complete control over the Wiki.js instance. The impact is significant as it compromises the integrity and security of the entire wiki platform.
Mitigation Recommendations
This vulnerability is fixed in Wiki.js version 2.5.313. Users should upgrade to version 2.5.313 or later to remediate this issue. Since no official patch link or advisory is provided, verify the upgrade availability from the official Wiki.js project resources. No temporary mitigations are indicated in the available data.
