# Strapi: webhook redirects let attackers reach internal network addresses

Strapi's webhook dispatcher follows HTTP redirects without rechecking whether the destination is a private or link-local address. An attacker who can trigger webhooks can make the server send requests to internal hosts and see error responses reflected back.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of the `@strapi/strapi` package with `npm ls @strapi/strapi`
- Confirm whether webhooks are configured in the admin panel under Settings, then Webhooks
- unknown whether a specific version range is affected, as the sources do not say

## Fix

- unknown: the sources do not name a patched version of `@strapi/strapi`; check the Strapi release notes or the advisory on NVD
- Until a fix is applied, restrict outbound network access from the Strapi server to internal ranges (RFC1918 and link-local)

## Timeline

## From the sources

The strapi/strapi (Core Admin / Webhook Runner) package is vulnerable to a semi-blind SSRF via a webhook follow-redirect. The webhook dispatcher automatically follows HTTP redirects without performing post-redirect IP resolution or RFC1918/link-local boundary checks. Non-2xx responses from target endpoints are captured and reflected directly back to the caller.
