CVE-2026-19285Public exploit

Local file read and overwrite via domain IDs

Published Aug 8, 2026 · Updated Aug 8, 2026

Path traversal in Aaron Bockelie memory-graph allows local users to read and overwrite files via crafted MCP domain IDs. The JSON backend passes the caller-controlled ID to path.join as the filename without verifying that the resolved path remains inside the memories directory. A malicious local MCP client with access to create_domain is required; the published evidence implicates the JSON backend rather than SQLite or MariaDB.
