CVE-2023-46128Public exploitNetwork attack vector

Hashed password disclosure via nested serializer inheritance

Published Oct 24, 2023 · Updated Sep 11, 2024

Information disclosure in Network to Code Nautobot 2.0.0 through 2.0.2 allows remote authenticated users to read stored password hashes. Nested serializers fail to inherit excluded fields from base serializer Meta classes, so depth expansion serializes User.password. The gate is authenticated access to an endpoint referencing User objects; exposure is limited to stored hashes rather than plaintext passwords.
