### Impact `context_import` passed the caller-supplied `filePath` directly to `fs.readFileSync` with no path confinement. A malicious MCP client — or an LLM agent that is prompt-injected into calling the tool — could point `filePath` at **any file readable by the server process**, outside any session or export directory: - **Full disclosure (JSON files):** a valid-JSON target (e.g. another user's exported session, or a `*.json` credential / service-account file) is parsed and imported into the caller's session, then retrievable verbatim via `context_get` / `context_export`. - **Partial disclosure (any file):** for a non-JSON target (e.g. `/etc/passwd`, an SSH key, a `.env`), `JSON.parse` throws and V8 includes a snippet of the file's leading bytes in the `SyntaxError` message, which was returned verbatim to the caller. Both `../` traversal and absolute paths worked — there was no path confinement of any kind. In a typical MCP deployment the server runs on the developer's machine, so the reachable set includes other users' exported memory sessions, JSON credential/config files, and (in leading-bytes form) `.env` files, SSH keys, and `/etc/passwd`. The trigger is a tool argument, so the realistic threat model is an LLM agent prompt-injected into calling `context_import`, or any MCP client connected to the server. ### Patches Fixed in **0.13.0** (PR #36): - Imports are confined to a server-owned exports directory (`<DATA_DIR>/exports`, overridable via `MEMORY_KEEPER_EXPORT_DIR`), resolved with `realpathSync`. `../` traversal, absolute paths outside the directory, and symlink escapes are all rejected. - File read and `JSON.parse` are separate operations; read/parse failures return a generic message and never echo file bytes (the `SyntaxError`-message leak is gone). The database-write path is likewise generic. - An E2E security regression suite covers the reported arbitrary-read and traversal vectors, plus symlink escape, the directory-prefix boundary, and a no-existence-oracle check. ### Workarounds Upgrade to **`>= 0.13.0`**. There is no configuration-only workaround for affected versions. ### Resources - Report: GitHub issue #35 - Fix: PR #36 ### Credit Reported by Zhihao Zhang ([@mcfly-zzh](https://github.com/mcfly-zzh)).
