We found that this vulnerability is present when the developer is implementing an OAuth 1 provider (by extension, it means Twitter, which is the only built-in provider using OAuth 1), but upgrading isstill recommended.
next-auth
v3 users before version 3.29.3 are impacted. (We recommend upgrading to v4, as v3 is considered unmaintained. See our migration guide)
next-auth
v4 users before version 4.3.3 are impacted.
We’ve released patches for this vulnerability in:
3.29.3
4.3.3
You can do:
npm i next-auth@latest
or
yarn add next-auth@latest
or
pnpm add next-auth@latest
(This will update to the latest v4 version, but you can change latest
to 3
if you want to stay on v3.)
If you are not able to upgrade for any reason, you can add the following configuration to your callbacks
option:
// async redirect(url, baseUrl) { // v3
async redirect({ url, baseUrl }) { // v4
// Allows relative callback URLs
if (url.startsWith("/")) return `${baseUrl}${url}`
// Allows callback URLs on the same origin
else if (new URL(url).origin === baseUrl) return url
return baseUrl
}
This vulnerability was discovered right after https://github.com/nextauthjs/next-auth/security/advisories/GHSA-f9wg-5f46-cjmw was published and is very similar in nature.
Read more about the callbacks.redirect
option in the documentation: https://next-auth.js.org/configuration/callbacks#redirect-callback
