| Title | DNS Rebinding via SSE Causing CORS Bypass in MCP Toolbox for Databases |
Wed, 27 May 2026 22:30:00 +0000
| Type | Values Removed | Values Added |
|---|---|---|
| Description | Vulnerable to DNS rebinding attacks when using SSE (http://b/499408790). During the beta phase, we implemented `allowed-origins` and `allowed-hosts` flags to align with MCP security guidelines. However, the hardcoded `Access-Control-Allow-Origin: *` header in the SSE initialization handler was inadvertently retained. This vulnerability specifically impacts users connecting via Toolbox using SSE under specification v2024-11-05. | |
