Incorrect Authorization

CVE-2026-46717

Low
0/10

Summary

nezha's dashboard supports two user roles: `RoleAdmin` (Role==0) and `RoleMember` (Role==1). The notification routes `POST /api/v1/notification` and `PATCH /api/v1/notification/:id` are wired through `commonHandler` rather than `adminHandler` -- so a `RoleMember` user can call them. These handlers synchronously `Send()` an HTTP request to a user-controlled URL and reflect the *entire* response body (no size limit) back to the caller on any non-2xx response. All versions prior to 2.0.8 are affected.

CWE-863 - Incorrect Authorization

Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
