Nautobot vulnerable to exposure of hashed user passwords via REST API

CVE-2023-46128 [HIGH] CWE-200 Nautobot vulnerable to exposure of hashed user passwords via REST API
Nautobot vulnerable to exposure of hashed user passwords via REST API
### Impact
In Nautobot 2.0.x, certain REST API endpoints, in combination with the `?depth=` query parameter, can expose hashed user passwords as stored in the database to any authenticated user with access to these endpoints.
> The passwords are *not* exposed in plaintext.
> Nautobot 1.x is *not* affected by this vulnerability.
Example:
```
GET /api/users/permissions/?depth=1
HTTP 200 OK
API-Version: 2.0
Allow: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
```

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
