SCA: security update for @modelcontextprotocol/sdk (GHSA-w48q-cv73-mx4w)

high Tenable Cloud Security Plugin ID 436188

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - MCP TypeScript SDK is the official TypeScript SDK for Model Context Protocol servers and clients. Prior to
 1.24.0, The Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by
 default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication
 with StreamableHTTPServerTransport or SSEServerTransport and has not enabled enableDnsRebindingProtection,
 a malicious website could exploit DNS rebinding to bypass same-origin policy restrictions and send
 requests to the local MCP server. This could allow an attacker to invoke tools or access resources exposed
 by the MCP server on behalf of the user in those limited circumstances. Note that running HTTP-based MCP
 servers locally without authentication is not recommended per MCP security best practices. This issue does
 not affect servers using stdio transport. This vulnerability is fixed in 1.24.0. (CVE-2025-66414)
