Research direction
Review the dotenv_values entry point and the path-handling behavior shown in the example. Done should establish a clear way to control relative-path searching and prevent unintended files such as /etc/passwd from being parsed or exposed; no test file is named in the issue.
Written by the indexing model from the issue text.
Description
Currently the user-specified path could point to any folder and dotenv will parse them anyway even if it is files like /etc/passwd.
The content of the target file would be available in the error message. This could potentially introduce the path traversal vulnerability if the developer misuses it.
from dotenv import load_dotenv
from dotenv import dotenv_values
import os
config = dotenv_values("../../../etc/passwd")
I am wondering if it is possible to give dotenv_values an additional arguments to control if it would support relative path searching.
