SCA: security update for netlicensing-mcp (GHSA-x9vc-9ffq-p3gj)

high Tenable Cloud Security Plugin ID 444719

Description

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

- NetLicensing MCP Server is a natural-language interface that enables agentic applications to manage the
software-licensing lifecycle in Labs64 NetLicensing. Prior to 0.1.6, network-reachable HTTP transport
requests to /mcp that omit x-netlicensing-api-key, Authorization: Bearer, and the apikey query parameter
pass through ApiKeyMiddleware in src/netlicensing_mcp/server.py without authentication. The downstream
api_key_ctx in src/netlicensing_mcp/client.py then falls back to the operator's NETLICENSING_API_KEY and
authenticates upstream NetLicensing REST API calls under the operator account. An unauthenticated attacker
can invoke MCP tools to enumerate products, licenses, licensees, and transactions, create or modify
licensing objects, perform validations, and execute destructive delete operations. The issue affects HTTP
deployments configured with a server-side key and does not require user interaction. This issue is fixed
in version 0.1.6. (CVE-2026-54446)

Solution

Update the netlicensing-mcp library and its related packages to version 0.1.6 or later.
