Mcp Server Dash
Monthly
DNS rebinding in Dropbox's mcp-server-dash (network mode) allows a malicious web page to reach the local MCP listener and invoke Dropbox API tools - company-search and file-detail - under the victim's stored Dropbox credential. The server bound to the loopback interface but performed no Host header validation, letting a browser issue cross-origin requests via a rebound domain that resolves to 127.0.0.1. No public exploit has been identified at time of analysis; CVSS 4.0 scores this at 2.3, reflecting the attack's prerequisites of user interaction and a specific deployment mode.
