Research direction

Start with package.json and the shown imageSize import, checking whether image-size is direct or transitive and whether the proposed override applies. Done means the vulnerable dependency is no longer resolved and the maintained package preserves the existing public API.

Written by the indexing model from the issue text.

Description

Context

This package depends on npm image-size. Upstream is archived and the latest release (2.0.2) remains affected by:

  • CVE-2025-71329 — DoS via infinite loop (JXL/HEIF/JP2 zero-size boxes)
  • CVE-2025-71330 — DoS via infinite loop (ICNS zero entry length)

npm audit fix will not switch package names automatically.

Maintained drop-in

Community MIT fork with the same public API as image-size@2.0.2:

Not affiliated with the original image-size maintainer — honest community fork only.

Migration options

A — Direct dependency

npm install image-size-next
- import { imageSize } from 'image-size'
+ import { imageSize } from 'image-size-next'

B — Force transitive resolution (npm 8.3+)

{
  "overrides": {
    "image-size": "npm:image-size-next@2.1.0"
  }
}
