CVE-2026-28684
6.6 · MEDIUMOverview
CVE-2026-28684 is a medium-severity vulnerability affecting saurabh-kumar python-dotenv. It was published on April 20, 2026 and has a CVSS 3.1 base score of 6.6 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.6, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from saurabh-kumar. Update python-dotenv to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
