Path Traversal

langchain is a Building applications with LLMs through composability

Affected versions of this package are vulnerable to Path Traversal due to improper limitation of a pathname to a restricted directory in its LocalFileStore functionality. An attacker can leverage this vulnerability to read or write files anywhere on the filesystem, potentially leading to information disclosure or remote code execution.

Note: The issue lies in the handling of file paths in the mset and mget methods, where user-supplied input is not adequately sanitized, allowing directory traversal sequences to reach unintended directories.

How to fix Path Traversal?

Upgrade langchain to version 0.0.353 or higher.
