GHSA-Q2MX-J4X2-2H74

Vulnerability from github – Published: 2022-05-24 22:03 – Updated: 2022-05-24 22:03
VLAI
Summary
URL Redirection to Untrusted Site ('Open Redirect') in next-auth
Details

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
}

References

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.

Timeline

The issue was reported 2022 April 20th, a response was sent out to the reporter 8 minutes after, and a patch was produced within a few days.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
