NextAuth.js default redirect callback vulnerable to open redirects

next-auth v3 users before version 3.29.2 are impacted. (We recommend upgrading to v4 in most cases. See our migration guide).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:

// 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.
