sharpReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
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?
Most people rely on the prebuilt binaries provided by sharp.
Please upgrade sharp to the latest 0.32.6, which provides libwebp 1.3.2.
Using a globally-installed libvips?
Please ensure you are using the latest libwebp 1.3.2.
Possible workaround
Add the following to your code to prevent sharp from decoding WebP images.
sharp.block({ operation: ["VipsForeignLoadWebp"] });

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sharp. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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.
How O3 protects you
O3 pinpoints whether GHSA-54xq-cgqr-rpm3 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-54xq-cgqr-rpm3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-54xq-cgqr-rpm3 in your dependencies?
O3 detects GHSA-54xq-cgqr-rpm3 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
