Version Details and Security Vulnerabilities

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"] });

Affected versions of yargs-parser are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --foo.__proto__.bar baz' adds a bar property with value baz to all objects. This is only exploitable if attackers have control over the arguments being passed to yargs-parser.

Recommendation

Upgrade to versions 13.1.2, 15.0.1, 18.1.1 or later.
