Summary: Improper CSP in Image Optimization API for Next.js versions between 10.0.0 and 12.1.0

Details: Next.js is a React framework. Starting with version 10.0.0 and prior to version 12.1.0, Next.js is vulnerable to User Interface (UI) Misrepresentation of Critical Information. In order to be affected, the `next.config.js` file must have an `images.domains` array assigned and the image host assigned in `images.domains` must allow user-provided SVG. If the `next.config.js` file has `images.loader` assigned to something other than default, the instance is not affected. Version 12.1.0 contains a patch for this issue. As a workaround, change `next.config.js` to use a different `loader configuration` other than the default. ### Impact - **Affected**: All of the following must be true to be affected - Next.js between version 10.0.0 and 12.0.10 - The `next.config.js` file has [images.domains](https://nextjs.org/docs/api-reference/next/image#domains) array assigned - The image host assigned in [images.domains](https://nextjs.org/docs/api-reference/next/image#domains) allows user-provided SVG - **Not affected**: The `next.config.js` file has [images.loader](https://nextjs.org/docs/api-reference/next/image#loader-configuration) assigned to something other than default ### Patches [Next.js 12.1.0](https://github.com/vercel/next.js/releases/tag/v12.1.0) ### Workarounds Change `next.config.js` to use a different [loader configuration](https://nextjs.org/docs/api-reference/next/image#loader-configuration) other than the default, for example: ```js module.exports = { images: { loader: 'imgix', path: 'https://example.com/myaccount/', }, } ``` Or if you want to use the [`loader`](https://nextjs.org/docs/api-reference/next/image#loader) prop on the component, you can use `custom`: ```js module.exports = { images: { loader: 'custom', }, } ```
