## Overview

Sharp before 0.35.4 bundles a vulnerable libheif dependency that allows attackers to achieve possible remote code execution on glibc-based Linux by supplying crafted images. Attackers can submit malicious AVIF/HEIF input to applications processing untrusted images with sharp, triggering libheif decoding flaws to execute code.

## Affected

- `sharp < 0.35.4`
