Next.js — открытый JavaScript фреймворк, созданный поверх React.js для создания веб-приложений

Open Redirect in Next.js

Next.js is an open source website development framework to be used with the React library. In affected versions specially encoded paths could be used when pages/_error.js was statically generated allowing an open redirect to occur to an external site. In general, this redirect does not directly harm users although can allow for phishing attacks by redirecting to an attacker's domain from a trusted domain. We recommend everyone to upgrade regardless of whether you can reproduce the issue or not. The issue has been patched in release 11.1.0.

Next.js versions >=9.5.0 and <9.5.4 are vulnerable to an Open Redirect. Specially encoded paths could be used with the trailing slash redirect to allow an open redirect to occur to an external site. In general, this redirect does not directly harm users although can allow for phishing attacks by redirecting to an attackers domain from a trusted domain. The issue is fixed in version 9.5.4.

Open Redirect in Next.js versions

Next.js versions before 9.3.2 have a directory traversal vulnerability. Attackers could craft special requests to access files in the dist directory (.next). This does not affect files outside of the dist directory (.next). In general, the dist directory only holds build assets unless your application intentionally stores other assets under this directory. This issue is fixed in version 9.3.2.
