Hi,

The following vulnerability was published for python-dotenv.

CVE-2026-28684[0]:
| 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.


If you fix the vulnerability please also make sure to include the
