SCA: security update for next-auth (GHSA-8fpg-xm3f-6cx3)

critical Tenable Self-Hosted Container Security Plugin ID 445217

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - NextAuth.js provides authentication for Next.js. From next-auth 5.0.0-beta.0 until 5.0.0-beta.32,
 applications that gate access by checking only for the existence of the auth object returned by the auth()
 wrapper can fail open when Auth.js has a server configuration error. In middleware, Route Handlers, React
 Server Components, and other auth() entry points, a non-OK session response is parsed into a truthy error
 object instead of null, so checks such as !!auth and if (req.auth) evaluate to true for unauthenticated
 requests. A provider missing both the issuer and authorization endpoint triggers InvalidEndpoints, and an
 unset AUTH_SECRET or another server configuration error can produce the same behavior. There is no impact
 while configuration is valid, but after a deployment becomes misconfigured, routes protected only by
 session existence silently grant access to every visitor. This issue is fixed in next-auth 5.0.0-beta.32.
 (CVE-2026-73421)

Solution

Update the next-auth library and its related packages to version 5.0.0-beta.32 or later.
