Summary: NextAuth.js default redirect callback vulnerable to open redirects

Details: `next-auth` v3 users before version 3.29.2 are impacted. (We recommend upgrading to v4 in most cases. See our [migration guide](https://next-auth.js.org/getting-started/upgrade-v4)).`next-auth` v4 users before version 4.3.2 are impacted. Upgrading to 3.29.2 or 4.3.2 will patch this vulnerability. If you are not able to upgrade for any reason, you can add a configuration to your `callbacks` option: ```js // async redirect(url, baseUrl) { // v3 async redirect({ url, baseUrl }) { // v4 // Allows relative callback URLs if (url.startsWith("/")) return new URL(url, baseUrl).toString() // Allows callback URLs on the same origin else if (new URL(url).origin === baseUrl) return url return baseUrl } ``` If you already have a `redirect` callback, make sure that you match the incoming `url` origin against the `baseUrl`.
