CVE-2024-3571 Path Traversal in langchain-ai/langchain

What is CVE-2024-3571?

CVE-2024-3571 is a medium-severity path traversal vulnerability in langchain-ai/langchain, published on 16 Apr 2024. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

langchain-ai/langchain is vulnerable to path traversal due to improper limitation of a pathname to a restricted directory ('Path Traversal') 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. 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.

Weakness: CWE-22
