{"id":"GHSA-3x59-vrmc-5mx6","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","aliases":["CVE-2023-41167"],"modified":"2026-07-08T06:28:43.333754822Z","published":"2023-08-24T22:16:20Z","database_specific":{"nvd_published_at":"2023-08-25T14:15:10Z","cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-08-24T22:16:20Z"},"references":[{"type":"WEB","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"},{"type":"WEB","url":"https://webiny.com"}],"affected":[{"package":{"name":"@webiny/react-rich-text-renderer","ecosystem":"npm","purl":"pkg:npm/%40webiny/react-rich-text-renderer"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"5.37.2"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 5.37.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/08/GHSA-3x59-vrmc-5mx6/GHSA-3x59-vrmc-5mx6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N"}]}
