CVE-2022-31093Improper Handling of `callbackUrl` parameter in next-auth
High 7.5
In plain English
A high-severity security flaw in next-auth from nextauthjs. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.7% (higher than 78% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
NextAuth.js is a complete open source authentication solution for Next.js applications. In affected versions an attacker can send a request to an app using NextAuth.js with an invalid `callbackUrl` query parameter, which internally is converted to a `URL` object. The URL instantiation would fail due to a malformed URL being passed into the constructor, causing it to throw an unhandled error which led to the **API route handler timing out and logging in to fail**. This has been remedied in versions 3.29.5 and 4.5.0. If for some reason you cannot upgrade, the workaround requires you to rely on Advanced Initialization. Please see the documentation for more.
