CVE-2026-122016: RuoYi-Vue improper privilege management in permission service

CVE-2026-122016 · Severity: medium · CVSS 6.3 · Published 2026-11-04

RuoYi-Vue is a permission management system based on Spring Boot, Spring Security, and JWT. A vulnerability in the permission service allows authenticated users with menu management privileges to escalate their own permissions to full administrative access by injecting a reserved wildcard (*:*:*) into the menu permissions field. An attacker can then access sensitive system functions including logs, server metrics, and database structure modifications.

Vendors: Yangzongzhuan.

How to fix

Restrict menu management and role editing privileges to trusted administrators only. Validate that the perms field in menu creation and update operations rejects the reserved wildcard *:*:* before persisting to the database.

Technical details

The vulnerability is an improper privilege management flaw (CWE-863/CWE-269) in the SysPermissionService.getMenuPermission function. The permission framework reserves the wildcard *:*:* as a marker for full admin access, but the menu permissions table accepts any input without validation. An authenticated user with menu and role management rights can create a menu with perms='*:*:*', assign it to their role, and gain full system permissions that pass all authorization checks. The attack requires prior authorization to system:menu:add/edit and system:role:edit with appropriate data scope.
