CVE-2026-61647
CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N
Summary
NotebookLM MCP is an MCP server and HTTP service for interacting with Google NotebookLM and exporting generated content to local vault directories. Versions 1.6.0 through 2.0.2 contain a path traversal vulnerability in the POST /batch-to-vault endpoint, also exposed through the batch_to_vault MCP tool beginning in version 1.7.0, because attacker-controlled vault_dir and slug_prefix values can cause Markdown and JSON files to be written outside the intended vault directory to any location writable by the server process. Version 2.0.3 sanitizes slug_prefix and supports vault containment when NOTEBOOKLM_VAULT_ROOT is configured; containment is not enabled if that variable is unset. Users unable to upgrade should run the server as a dedicated unprivileged account restricted to the intended vault, keep the HTTP endpoint limited to localhost, and validate vault_dir values supplied by LLMs processing untrusted content.
