概要
python-dotenv: Symlink following in set_key allows arbitrary file overwrite via cross-device rename fallback
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
python-dotenv reads key-value pairs from a .env file and can set them as environment variables. Prior to version 1.2.2, set_key() and unset_key() in python-dotenv follow symbolic links when rewriting .env files, allowing a local attacker to overwrite arbitrary files via a crafted symlink when a cross-device rename fallback is triggered. Users should upgrade to v.1.2.2 or, as a workaround, apply the patch manually.
