{"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":"@webiny/react-rich-text-renderer before 5.37.2 allows XSS attacks by content managers. This is a react component to render data coming from Webiny Headless CMS and Webiny Form Builder. Webiny is an open-source serverless enterprise CMS. The @webiny/react-rich-text-renderer package depends on the editor.js 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.","published":"2023-08-25T00:00:00Z","modified":"2026-07-15T01:48:58.924261746Z","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":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:58.924261746Z"}}
