CVE-2026-46717: CWE-863: Incorrect Authorization in nezhahq nezha
Nezha Monitoring versions from 1.4.0 up to but not including 2.0.8 contain an authorization vulnerability in the dashboard's notification routes. RoleMember users can access POST and PATCH notification endpoints intended for administrators, allowing them to trigger HTTP requests to user-controlled URLs and receive the full response body on non-2xx responses. This issue was addressed in version 2.0.8.
AI Analysis
Technical Summary
Nezha Monitoring is a self-hosted monitoring tool with two user roles: RoleAdmin and RoleMember. In versions >=1.4.0 and <2.0.8, the notification API endpoints POST /api/v1/notification and PATCH /api/v1/notification/:id are handled by a commonHandler accessible to RoleMember users instead of the adminHandler. This improper authorization allows RoleMember users to invoke these endpoints, causing the server to synchronously send HTTP requests to URLs controlled by the user and reflect the entire response body back to the caller if the response status is non-2xx. This vulnerability is classified under CWE-863 (Incorrect Authorization) and CWE-918 (Server-Side Request Forgery). The vulnerability was fixed in version 2.0.8.
Potential Impact
An attacker with RoleMember privileges can exploit this vulnerability to cause the server to make HTTP requests to arbitrary URLs controlled by the attacker and receive the full response body on error responses. This could lead to information disclosure or other impacts depending on the target of the server-side requests. The CVSS 3.1 score is 7.7 (high), reflecting network attack vector, low attack complexity, low privileges required, no user interaction, scope change, and high confidentiality impact without integrity or availability impact.
Mitigation Recommendations
Upgrade Nezha Monitoring to version 2.0.8 or later, where this authorization issue has been fixed. No other mitigation steps are indicated by the vendor advisory. Patch status is confirmed by the version-based fix information.
