Summary

## Impact A memory-related vulnerability has been discovered in an upstream library used for Image Optimization can lead to possible remote code execution (RCE) when Next.js runs on glibc-based Linux. ## Workaround Ensure the version of `sharp` used by Next.js is greater than or equal to `0.35.5`. Fresh installs automatically get a fixed version of `sharp`. Upgrading Next.js to the patched versions will ensure package managers automatically provide a fixed version of `sharp` to Next.js.
