## Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in Nautobot's Webhook data model (CWE-918). Users with 'add' or 'change' permissions for webhooks can configure the system to perform requests to arbitrary hosts, IP addresses, or URI schemes that should be restricted. This occurs because the application does not sufficiently validate the destination of webhook requests. Attackers can leverage this to probe internal networks or access metadata services. Patches in v2.4.33 and v3.1.2 introduce new configuration variables (WEBHOOK_ALLOWED_SCHEMES, WEBHOOK_ADDITIONAL_BLOCKED_NETWORKS, and WEBHOOK_ALLOWED_HOSTS) to enforce strict allow-lists and block-lists for webhook destinations.
