Overview
sharp uses libwebp to decode WebP images and versions prior to the latest 0.32.6 are vulnerable to the high severity https://github.com/advisories/GHSA-j7hp-h8jx-5ppr.
Who does this affect?
Almost anyone processing untrusted input with versions of sharp prior to 0.32.6.
How to resolve this?
Using prebuilt binaries provided by sharp?

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sharp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update sharp to 0.32.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-54xq-cgqr-rpm3 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
