GHSA-xmpv-j7p2-j873: nautobot (CVE-2026-34203)

Package	Ecosystem	Affected	Fixed in
nautobot	PyPI	<2.4.30 \|\| >=3.0.0, <3.0.10	2.4.30, 3.0.10

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nautobot versions prior to 2.4.30 and 3.0.0 through 3.0.9 do not apply Django's configured password validators when users are created or edited through the REST API, so weak passwords can be set. The source describes this as a low-severity issue (CVSS 3.1 base score 2.7); the attacker needs access to a REST API account with permission to manage users. Upgrade to Nautobot 2.4.30 or 3.0.10. As a workaround, review which users can create or modify user accounts through the API and restrict that access, and rotate passwords for accounts that may have weak passwords.
