CVE-2024-39693Network attack vector

Unauthenticated application server crash

Published Jul 10, 2024 · Updated Nov 5, 2024

Uncontrolled resource consumption in Vercel Next.js 13.3.1 through 13.4.x allows remote attackers to crash the application server. The upstream advisory does not disclose the request form, affected handler, or resource operation that exhausts or destabilizes the server. Any unauthenticated network client that can reach an affected deployment can interrupt application availability, with no reported data access or modification.
