Error: Vulnerable version of Next.js detected, please update immediately. Learn More: https://vercel.link/CVE-2025-66478
I can see the current Next.js version is 15.5.6, which is within the vulnerable range. According to the security bulletin, Next.js 15.5.x needs to be updated to 15.5.7 (the patched version). Let me update this immediately.
I've updated Next.js from version 15.5.6 to 15.5.7, which includes the security patch for CVE-2025-66478. This patched version hardens the React Server Components implementation to prevent the vulnerability. Your deployment should now succeed without the security warning.
I've upgraded Next.js from 15.5.7 to 15.5.9.
