{"cve":"CVE-2026-41692","nvd":{"published":"2026-05-07T21:16:29.717","modified":"2026-10-26T20:10:00.160","status":"Analyzed","description":"i18nextify is a JavaScript library that adds website internationalization via a script tag, without source code changes. Versions prior to 4.0.8 substitute {{key}} interpolation tokens inside src and href attribute values with the raw string returned by i18next.t(). The substitution logic in src/localize.js (the replaceInside handler) only guards against a duplicated http:// origin prefix — it does not validate the URL scheme of the substituted value. A translated value such as javascript:alert(1) or data:text/html,<script>...</script> is applied unchanged to the live DOM attribute when an attacker can influence the content of a translation file or the translation-backend response — for example, via a compromised translation CDN, user-contributed locales, a MITM on a plain-HTTP backend, or write access to the translation JSON. This issue was patched in version 4.0.8.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7},"cwes":["CWE-79","CWE-94"],"references":["https://github.com/i18next/i18nextify/commit/16f23dbcdcf893673587f7a03355bf7ce0a0e49e","https://github.com/i18next/i18nextify/security/advisories/GHSA-6457-mxpq-4fqq"],"products":["i18next:i18nextify"],"source":"nvd","synced_at":"2026-10-26T20:34:58.897451322+00:00"},"epss":{"cve":"CVE-2026-41692","score":0.00144,"percentile":0.03669,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-6457-mxpq-4fqq","url":"https://osv.dev/vulnerability/GHSA-6457-mxpq-4fqq","summary":"i18nextify has DOM XSS via javascript:/data: URL schemes in translated href/src attributes","modified":"2026-05-11T13:53:13.645066Z","packages":[{"ecosystem":"npm","name":"i18nextify","purl":"pkg:npm/i18nextify","ranges":["<4.0.8"],"fixed":["4.0.8"]}]}],"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).
