SCA: security update for meta-ads-mcp (GHSA-9gw6-46qc-99vr)

critical Tenable Self-Hosted Container Security Plugin ID 443071

Description

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

 - Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to
 version 1.0.109, `AuthInjectionMiddleware.dispatch()` at `http_auth_integration.py:272` unconditionally
 forwards unauthenticated Streamable HTTP requests to downstream MCP tool handlers without issuing a `401`
 response, allowing any network-reachable caller to invoke MCP tools without authentication. When no per-
 request credential is present, tool handlers fall back to the `META_ACCESS_TOKEN` environment variable,
 and when the downstream Meta Graph API call fails, `api.py:263–269` serialises the raw `httpx` request
 URL—including the operator's `access_token` as a query parameter—into the JSON-RPC response body,
 delivering the credential to the unauthenticated caller. Version 1.0.109 fixes the issue. (CVE-2026-48039)

Solution

Update the meta-ads-mcp library and its related packages to version 1.0.109 or later.
