    Summary: Next.js: Unauthenticated Remote Code Execution in Image Optimization API when AVIF files are used

    Details: A vulnerability in the underlying `libheif` library used by `sharp` which Next.js uses for image optimization can lead to remote code execution when AVIF files are optimized. Until a fix has propagated, optimization of AVIF files is disabled.
