[Security] Bump next from 15.1.2 to 15.2.4

Ronan Amicel requested to merge dependabot-npm_and_yarn-next-15.2.4 into main

Bumps next from 15.1.2 to 15.2.4. This update includes a security fix.

Vulnerabilities fixed

Authorization Bypass in Next.js Middleware

Impact

It is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware.

Patches

  • For Next.js 15.x, this issue is fixed in 15.2.3
  • For Next.js 14.x, this issue is fixed in 14.2.25
  • For Next.js 13.x, this issue is fixed in 13.5.9
  • For Next.js 12.x, this issue is fixed in 12.3.5
  • For Next.js 11.x, consult the below workaround.

Note: Next.js deployments hosted on Vercel are automatically protected against this vulnerability.

Workaround

If patching to a safe version is infeasible, it is recommend that you prevent external user requests which contain the x-middleware-subrequest header from reaching your Next.js application.
