This vulnerability has a CVSS 3.1 base score of 9.1, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
A Server-Side Request Forgery (SSRF) vulnerability was identified in the @opennextjs/cloudflare package. The vulnerability stems from an unimplemented feature in the Cloudflare adapter for Open Next, which allowed unauthenticated users to proxy arbitrary remote content via the /_next/image endpoint.
This issue allowed attackers to load remote resources from arbitrary hosts under the victim site’s domain for any site deployed using the Cloudflare adapter for Open Next.
For example:
https://victim-site.com/_next/image?url=https://attacker.com
In this example, attacker-controlled content from attacker.com is served through the victim site’s domain (victim-site.com), violating the same-origin policy and potentially misleading users or other services.
Impact:
* SSRF via unrestricted remote URL loading
* Arbitrary remote content loading
* Potential internal service exposure or phishing risks through domain abuse
Mitigation:
