CVE-2026-28684 not yet assigned priority: Debian including 1 source packages (python-dotenv), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
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.
