CVE-2026-28684 (GCVE-0-2026-28684)
Vulnerability from cvelistv5

CWE
  • CWE-59 - Improper Link Resolution Before File Access ('Link Following')
  • CWE-61 - UNIX Symbolic Link (Symlink) Following
Summary
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.
