CVE-2026-9739
MCP Toolbox for Databases vulnerable to DNS rebinding attacks
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon GHSA.
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.
