SCA: security update for @andrea9293/mcp-documentation-server (GHSA-6f5r-5672-72j7)

high Tenable Self-Hosted Container Security Plugin ID 444850

Description

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

- MCP Documentation Server is a local-first document management and semantic search server for AI coding
agents. From 1.13.0 until 1.13.1, the automatically started Web UI in src/server.ts calls startWebServer
in src/web-server.ts with START_WEB_UI enabled by default and WEB_PORT set to 3080. startWebServer uses
app.listen(PORT) without a host, which binds the unauthenticated document-management API to all interfaces
rather than localhost. A network-reachable client can invoke GET /api/documents, GET /api/documents/:id,
POST /api/documents, POST /api/search-all, DELETE /api/documents/:id, and GET /api/config without
credentials to enumerate and read documents, search the corpus, insert or delete documents, and tamper
with the MCP assistant's knowledge base. The service must be reachable from the attacker's LAN, VM
network, container bridge, VPN, or another routed network, and the issue does not provide remote code
execution. This issue is fixed in 1.13.1. (CVE-2026-54504)

Solution

Update the @andrea9293/mcp-documentation-server library and its related packages to version 1.13.1 or later.
