How to Fix GHSA-f88m-g3jw-g9cj

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: 0.35.0 
npm install sharp@0.35.0
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-f88m-g3jw-g9cj, 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 0.35.0), 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1395: Dependency on Vulnerable Third-Party Component, where the product has a dependency on a third-party component that contains one or more known vulnerabilities. In Sharp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A number of vulnerabilities, two rated as "High" severity using CVSSv4, have been discovered and fixed in the upstream libvips dependency. Those processing untrusted input with versions of sharp prior to 0.35.0 are affected. ### Patches #### Using prebuilt binaries provided by sharp? Most people rely on the prebuilt binaries provided by sharp. Please upgrade sharp to the latest version, currently 0.35.3, which provides libvips 8.18.3. #### Using a globally-installed libvips? Please ensure you are using the latest libvips 8.18.3. ### Workarounds Add the following to your code to prevent sharp from decoding GIF, TIFF and VIPS images. ```js sharp.block({ operation: ["VipsForeignLoadNsgif", "VipsForeignLoadTiff", "VipsForeignLoadVips"] }); ```
