GHSA-q2mx-j4x2-2h74: URL Redirection to Untrusted Site ('Open Redirect') in next-auth
Impact
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 is still 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.
Patches
We’ve released patches for this vulnerability in:
- v3 -
3.29.3
- v4 -
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.)
Workarounds
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
}
