Overview
@opennextjs/cloudflare is a Cloudflare builder for next apps
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the cdn-cgi/image/ handler due to improper path normalization. An attacker can cause the server to fetch arbitrary remote URLs and potentially expose internal or private resources by sending specially crafted requests with backslashes in the path.
Note:
This is only exploitable if the HTTP client preserves backslashes in the request path (such as using curl --path-as-is).
