How to Fix GHSA-54xq-cgqr-rpm3

To remediate this vulnerability, upgrade all affected Sharp dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

sharp fixed: 0.32.6 
npm install sharp@0.32.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls sharp

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-54xq-cgqr-rpm3, inspect your project dependencies using npm:

npm ls sharp

Analyze the terminal output to locate any version of Sharp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.32.6), your application is affected.

Note: The npm ls sharp command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Source Advisory Statement

## 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. ```js sharp.block({ operation: ["VipsForeignLoadWebp"] }); ```
