Ein Angreifer kann mehrere Schwachstellen in Vercel Next.js ausnutzen, um Sicherheitsvorkehrungen zu umgehen, Cross-Site-Scripting-Angriffe durchzuführen, Daten zu manipulieren, vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand zu verursachen.

Editorial Analysis

Why it matters

Next.js powers many European enterprise web applications; chained auth-bypass and XSS flaws can expose customer data and trigger GDPR notification obligations.

What to do

Inventory all Next.js deployments and apply vendor patches immediately; review WAF rules for XSS and auth-bypass patterns.

Board brief

Multiple high-severity web-framework vulnerabilities may expose customer-facing applications to data theft if unpatched.
