{"id":"CVE-2023-41167","aliases":["GHSA-3x59-vrmc-5mx6"],"url":"https://o3.security/vulnerability/CVE-2023-41167","summary":"@webiny/react-rich-text-renderer vulnerable to insecure rendering of rich text content","details":"## Overview\n`@webiny/react-rich-text-renderer` is a react component to render data coming from Webiny Headless CMS and Webiny Form Builder. The `@webiny/react-rich-text-renderer` package depends on the [editor.js](https://editorjs.io/) rich text editor to handle rich text content. The CMS stores rich text content from the `editor.js` into the database. When the `@webiny/react-rich-text-renderer` is used to render such content, it uses the `dangerouslySetInnerHTML` prop, without applying HTML sanitization. The issue arises when an actor, who in this context would specifically be a content manager with access to the CMS, inserts a malicious script as part of the user-defined input. This script is then injected and executed within the user's browser when the main page or admin page loads.\n\n## Am I affected?\nYou will be affected if you're running a Webiny project created prior to `5.35.0` and you're using the legacy rich text editor (which uses `editor.js` library under the hood). If you've already switched to using the new rich text editor, powered by Lexical editor, you will not be affected by this.\n\n## How do I patch this vulnerability?\nUpdate to Webiny version `5.37.2`.\n","published":"2023-08-25T00:00:00Z","modified":"2026-08-12T03:51:15.360649179Z","cvss":{"score":4.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@webiny/react-rich-text-renderer","fixedVersion":"5.37.2"}],"fix":{"url":"https://github.com/webiny/webiny-js/commit/8748bc53fe862bb03d4459ccc0be39084a5d35c0","label":"webiny/webiny-js@8748bc5"},"references":[{"type":"WEB","url":"https://webiny.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/41xxx/CVE-2023-41167.json"},{"type":"ADVISORY","url":"https://github.com/webiny/webiny-js/security/advisories/GHSA-3x59-vrmc-5mx6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-41167"},{"type":"WEB","url":"https://github.com/webiny/webiny-js/commit/8748bc53fe862bb03d4459ccc0be39084a5d35c0"},{"type":"PACKAGE","url":"https://github.com/webiny/webiny-js"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:15.360649179Z"}}
