Описание
Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, a rewrites() or redirects() rule that builds its external destination hostname from request-controlled input can be pointed at an arbitrary hostname, regardless of the rule's hostname suffix. For a rewrite, Next.js proxies the request to that arbitrary host and serves the response from the application's origin, leading to Server-Side Request forgery. A redirects() rule configured this way is vulnerable to an Open Redirect. This issue has been fixed in versions 15.5.21 and 16.2.11.

A flaw was found in Next.js, a React framework for building web applications. This vulnerability allows a remote attacker to perform Server-Side Request Forgery (SSRF) or Open Redirect attacks. When a `rewrites()` or `redirects()` rule constructs an external destination hostname using attacker-controlled input, the application can be coerced into proxying requests to arbitrary hosts, leading to SSRF. Additionally, this misconfiguration can result in Open Redirects, potentially exposing users to phishing.
