| Impact | This is a low-severity but legitimate integrity issue. CVSS vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N reflects network-accessible REST API (AV:N), low attack complexity (AC:L), but critically requires high privileges (PR:H)-meaning only authenticated users with administrative role can exploit it. EPSS data is not provided, but the low CVSS (2.7) and privileged-access requirement suggest limited real-world exploitation risk for most organizations. However, the integrity impact (I:L) is meaningful: any organization with configured password policies specifically to enforce security standards faces a gap where REST API automation could circumvent those controls. This is less of an active threat and more of a configuration enforcement failure. The exploit requires deliberate misuse by an insider admin, not a network-based attacker. Risk priority depends on whether the organization relies on Nautobot's configured validators for compliance or policy enforcement; if so, remediation is important for integrity assurance; if not, the risk is minimal. |
| Exploit ScenarioDerived | An authenticated Nautobot administrator with user management privileges uses the REST API to programmatically create a new network operator account via POST /api/users/, intentionally specifying a simple or dictionary-based password such as 'password123' that would be rejected by the organization's configured AUTH_PASSWORD_VALIDATORS (e.g., a policy requiring 16+ characters and special symbols). The REST API accepts the request and creates the account with the weak password, whereas the same action attempted through the web UI would be rejected with a validation error. The weak password increases the risk of account compromise via brute force or credential stuffing if the account is later exposed or if the admin later grants the account higher privileges. |

Alert meAnalysisAIv1 – Mar 31, 2026
Nautobot REST API user creation and modification endpoints bypass Django's configured password validation rules, allowing authenticated administrators to set or modify user passwords that fail to meet organizational security standards. Versions prior to 2.4.30 and 3.0.10 are affected; an authenticated admin with high privileges can create accounts with weak passwords despite configured AUTH_PASSWORD_VALIDATORS rules. CVSS score is 2.7 (low severity) due to requirement for authenticated administrative access; however, organizations with strict password policies relying on Nautobot's config-driven enforcement face integrity risk.
RemediationAI
Upgrade Nautobot to version 2.4.30 or later (for 2.4.x deployments) or version 3.0.10 or later (for 3.0.x deployments). Both patched releases restore password validation enforcement in REST API user creation and modification endpoints by integrating Django's AUTH_PASSWORD_VALIDATORS into the API handlers, ensuring consistency with web UI behavior. No workarounds are available prior to patching; administrators cannot selectively disable REST API access to mitigate the gap. After upgrading, verify that any configured AUTH_PASSWORD_VALIDATORS in nautobot_config.py are properly applied to both UI and API user operations. Refer to the fix pull requests at https://github.com/nautobot/nautobot/pull/8778 and https://github.com/nautobot/nautobot/pull/8779 for technical implementation details.

Technical ContextAI · show details
Nautobot is a Python-based network source-of-truth and automation platform that exposes user management capabilities via REST API endpoints. The vulnerability stems from a failure to invoke Django's AUTH_PASSWORD_VALIDATORS during REST API user creation and modification operations, even though these validators are correctly applied through Nautobot's web UI and can be configured in nautobot_config.py to enforce rules such as minimum length, complexity requirements, or dictionary checks. CWE-521 (Weak Password Requirements) identifies the root cause: the REST API handlers do not call the same validation pipeline used by the web interface, creating a security logic gap. The vulnerability affects all versions prior to the patched releases 2.4.30 and 3.0.10.

Lifecycle Timeline
4DescriptionNVD
Nautobot is a Network Source of Truth and Network Automation Platform. Prior to versions 2.4.30 and 3.0.10, user creation and editing via the REST API fails to apply the password validation rules defined by Django's AUTH_PASSWORD_VALIDATORS setting (which defaults to an empty list, i.e., no specific rules, but can be configured in Nautobot's nautobot_config.py to apply various rules if desired). This can potentially allow for the creation or modification of users to have passwords that are weak or otherwise do not comply with configured standards. This issue has been patched in versions 2.4.30 and 3.0.10.
