CVE-2026-29787Network attack vector

System information disclosure via detailed health endpoint

Published Mar 7, 2026 · Updated Mar 7, 2026

Information disclosure in mcp-memory-service before 10.21.0 allows remote attackers to read host details via a health API request. The /api/health/detailed handler returns OS and Python versions, resource totals, disk usage, and the database's absolute path without filtering sensitive fields. Anonymous access must be enabled, and the default all-interface binding exposes the response across the network, revealing host fingerprinting and filesystem-layout data.
