SCA: security update for mcp-memory-service (GHSA-73hc-m4hx-79pj)

medium Tenable Cloud Security Plugin ID 438429

Description

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

- mcp-memory-service is an open-source memory backend for multi-agent systems. Prior to version 10.21.0, the
/api/health/detailed endpoint returns detailed system information including OS version, Python version,
CPU count, memory totals, disk usage, and the full database filesystem path. When
MCP_ALLOW_ANONYMOUS_ACCESS=true is set (required for the HTTP server to function without OAuth/API key),
this endpoint is accessible without authentication. Combined with the default 0.0.0.0 binding, this
exposes sensitive reconnaissance data to the entire network. This issue has been patched in version
10.21.0. (CVE-2026-29787)

Solution

Update the mcp-memory-service library and its related packages to version 10.21.0 or later.
