{"id":"CVE-2022-23646","aliases":["GHSA-fmvm-x8mv-47mj"],"url":"https://o3.security/vulnerability/CVE-2022-23646","summary":"Improper CSP in Image Optimization API for Next.js","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.\n\n### Impact\n- **Affected**: All of the following must be true to be affected\n  - Next.js between version 10.0.0 and 12.0.10\n  - The `next.config.js` file has [images.domains](https://nextjs.org/docs/api-reference/next/image#domains) array assigned\n  - The image host assigned in [images.domains](https://nextjs.org/docs/api-reference/next/image#domains) allows user-provided SVG\n- **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\n\n### Patches\n[Next.js 12.1.0](https://github.com/vercel/next.js/releases/tag/v12.1.0)\n\n### Workarounds\nChange `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:\n\n```js\nmodule.exports = {\n  images: {\n    loader: 'imgix',\n    path: 'https://example.com/myaccount/',\n  },\n}\n```\n\nOr if you want to use the [`loader`](https://nextjs.org/docs/api-reference/next/image#loader) prop on the component, you can use `custom`:\n```js\nmodule.exports = {\n  images: {\n    loader: 'custom',\n  },\n}\n```\n\n","published":"2022-02-17T20:35:12Z","modified":"2026-08-12T03:51:17.496249776Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"next","fixedVersion":"12.1.0"}],"fix":{"url":"https://github.com/vercel/next.js/pull/34075","label":"vercel/next.js#34075"},"references":[{"type":"WEB","url":"https://github.com/vercel/next.js/releases/tag/v12.1.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23646.json"},{"type":"ADVISORY","url":"https://github.com/vercel/next.js/security/advisories/GHSA-fmvm-x8mv-47mj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23646"},{"type":"FIX","url":"https://github.com/vercel/next.js/pull/34075"},{"type":"PACKAGE","url":"https://github.com/vercel/next.js"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.496249776Z"}}
