    Microsoft Playwright MCP Server vulnerable to DNS Rebinding Attack; Allows Attackers Access to All Server Tools

    CVE-2025-9611 · GHSA-6fg3-hvw7-2fwq

    Affected
    • npm @playwright/mcp < 0.0.40
    Fixed in
    0.0.40· Vendor fix available
    Issue
    Microsoft Playwright MCP Server versions prior to 0.0.40 fails to validate the Origin header on incoming connections. This allows an attacker to perform a DNS rebinding attack via a victim’s web browser and send unauthorized requests to a locally running MCP server, resulting in unintended invocation of MCP tool endpoints.

    Recommended action: Upgrade to 0.0.40 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
