Routine

HIGH 8.9

CVE-2026-114112 is a high-severity flaw (CVSS 8.9) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Why this priority

High severity

A fixed release or distro patch exists.
