AI-suggested
Version 2.0.3 of notebooklm-mcp includes an official fix that sanitizes inputs and supports vault containment when the NOTEBOOKLM_VAULT_ROOT environment variable is configured. Users are advised to upgrade to version 2.0.3 or later. For those unable to upgrade immediately, it is recommended to run the server as a dedicated unprivileged account restricted to the intended vault directory, limit the HTTP endpoint to localhost, and validate 'vault_dir' values supplied by LLMs processing untrusted content.
Description
A path traversal vulnerability exists in roomi-fields notebooklm-mcp versions 1.6.0 through 2.0.2 in the POST /batch-to-vault endpoint and the batch_to_vault MCP tool starting from version 1.7.0. This flaw allows attacker-controlled inputs to cause files to be written outside the intended vault directory. Version 2.0.3 introduces sanitization and containment features to mitigate this issue. Users unable to upgrade should restrict server permissions and limit endpoint exposure.
