Description
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.
