The vulnerability has been remediated by upgrading to the patched version (15.5.7) as specified in the advisory guidelines. The project does not use React Flight packages, so no additional changes were required beyond the Next.js upgrade. All changes have been tested and the project builds successfully with the patched versions. Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
