CyberRota Analysis
AI-GeneratedNext.js versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10 are vulnerable to server-side request forgery (SSRF) and open redirect attacks due to improperly handled rewrites() and redirects() rules that allow request-controlled input to dictate external destination hostnames. This vulnerability enables an attacker to proxy requests to arbitrary hosts, potentially exposing sensitive data or redirecting users to malicious sites. Organizations using affected versions should prioritize updating to versions 15.5.21 or 16.2.11 to mitigate these risks.

Original NVD Description
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.
