SCA: security update for mcp-pinot-server (GHSA-73cv-556c-w3g6)

critical Tenable Cloud Security Plugin ID 444063

Description

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

 - mcp-pinot is a Python-based Model Context Protocol (MCP) server for interacting with Apache Pinot. In
 versions 3.0.1 and below, mcp-pinot defaults to running an HTTP MCP server bound to 0.0.0.0:8080 with no
 authentication enabled. All MCP tools, including SQL query execution, schema creation, and table-config
 mutation, are reachable by any network-adjacent caller. The server proxies these calls using server-side
 Pinot credentials, producing a confused-deputy condition that yields full read/write access to the
 configured Pinot cluster. This issue has been fixed in version 3.1.0 (CVE-2026-49257)

Solution

Update the mcp-pinot-server library and its related packages to version 3.1.0 or later.
