Ruoyi-Vue-Pro Mock Token Authentication Bypass (CVE-2026-XXXX) Analysis and PoC

CVE Report: Ruoyi-Vue-Pro Mock Token Authentication Bypass Vulnerability Vulnerability Overview Vulnerability Title: [Critical] Ruoyi-Vue-Pro Mock Token Authentication Bypass Vulnerability Vulnerability ID: CVE-2026-XXXX (Specific CVE number not assigned in the report, but mentions a CVE ID has been allocated) Severity: Critical (CVSS 3.1: 9.8) Affected Product: Ruoyi-Vue-Pro Affected Versions: 3.5.0 - 3.8.0 Vulnerability Description: A critical authentication bypass vulnerability exists in . An attacker can directly extract the user ID and forge an authentication object by sending a special request header, thereby bypassing the normal JWT token verification process and gaining administrator privileges without any environment verification or authentication. Impact Scope Affected Components: File: Method: Class: API: All API endpoints requiring authentication Attack Vector: 1. Authentication: No authentication required 2. Input Injection: Attacker sends a request header with the desired user ID 3. Execution: Server processes the request header and creates an authentication object 4. Impact: Attacker can access the system as any user (including administrators) CVSS 3.1 Vector String: CWE Classification: CWE-287: Improper Authentication CAPEC-112 Remediation Plan Recommended Fixes 1. Environment Isolation Control: Enable Mock Token only in non-production environments and validate the user ID. 2. Remove Mock Token Functionality: Completely remove the Mock Token code block in production environments and use standard JWT authentication. Additional Security Measures 1. Use separate configuration files for environment isolation. 2. Establish a configuration review process before deployment. 3. Implement a centralized configuration center for environment management. 4. Regularly scan production environments to detect test code. 5. Implement code review mechanisms to ensure test code does not enter production. 6. Log and monitor authentication bypass attempts. Proof of Concept (PoC) Code Step 1: Obtain Current User Information Step 2: Modify Any User's Password Step 3: Obtain User Permissions Expected Results Successful bypass of authentication and access to the system as any user Ability to access administrative functions requiring specific permissions Ability to retrieve sensitive information
