{"cve":"CVE-2023-41167","nvd":{"published":"2023-08-25T14:15:10.150","modified":"2026-06-17T06:20:51.627","status":"Modified","description":"@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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","score":4.8},"cwes":["CWE-79"],"references":["https://github.com/webiny/webiny-js/security/advisories/GHSA-3x59-vrmc-5mx6","https://webiny.com","https://github.com/webiny/webiny-js/security/advisories/GHSA-3x59-vrmc-5mx6","https://webiny.com"],"products":["webiny:webiny"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-41167","score":0.00392,"percentile":0.33421,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-3x59-vrmc-5mx6","url":"https://osv.dev/vulnerability/GHSA-3x59-vrmc-5mx6","summary":"@webiny/react-rich-text-renderer vulnerable to insecure rendering of rich text content","modified":"2026-07-08T06:28:43.333754822Z","packages":[{"ecosystem":"npm","name":"@webiny/react-rich-text-renderer","purl":"pkg:npm/%40webiny/react-rich-text-renderer","ranges":["<5.37.2"],"fixed":["5.37.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
