The /api/health/detailed endpoint in mcp-memory-service prior to version 10.21.0 discloses sensitive system information including OS details, Python version, CPU configuration, memory metrics, and database paths to unauthenticated network users when anonymous access is enabled. Public exploit code exists for this information disclosure vulnerability, which affects deployments using the default 0.0.0.0 network binding. A patch is available in version 10.21.0 to restrict endpoint access and redact sensitive data.

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.
Executive ViewAI
Organizations using mcp-memory-service should be aware of moderate risk from CVE-2026-29787, a information exposure vulnerability rated CVSS 5.3. Sensitive information could be exposed to unauthorized parties. Proof-of-concept code is publicly available. A patch is available and should be applied during regular vulnerability management.
Apply vendor patch. If patching is delayed: restrict endpoint access, redact sensitive data in logs.
