{"cve":"CVE-2026-41885","nvd":{"published":"2026-05-08T16:16:11.913","modified":"2026-10-26T18:10:00.173","status":"Deferred","description":"i18next-locize-backend is a simple i18next backend for locize.com which can be used in Node.js, in the browser and for Deno. Prior to version 9.0.2, i18next-locize-backend interpolates lng, ns, projectId, and version directly into the configured loadPath / privatePath / addPath / updatePath / getLanguagesPath URL templates with no path-component validation and no encoding. When an application exposes any of these values to user-controlled input (?lng= / ?ns= query parameters via i18next-browser-languagedetector, cookies, request headers, or a URL-derived projectId), a crafted value can change the structure of the outgoing request URL. Affected call sites in lib/index.js (pre-patch): the interpolate() helper is used at the five URL-build sites — _readAny/read (line 415 for private, 426 for public), getLanguages (lines 271 and 296), and writePage (lines 616 and 622) for the missing-key and update POST paths. The helper interpolate in lib/utils.js substitutes raw values with no encoding. This issue has been patched in version 9.0.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-22","CWE-74"],"references":["https://github.com/locize/i18next-locize-backend/security/advisories/GHSA-mgcp-mfp8-3q45"],"products":[],"source":"nvd","synced_at":"2026-10-26T18:27:13.530666824+00:00"},"epss":{"cve":"CVE-2026-41885","score":0.00224,"percentile":0.1287,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-mgcp-mfp8-3q45","url":"https://osv.dev/vulnerability/GHSA-mgcp-mfp8-3q45","summary":"i18next-locize-backend has URL Injection via Unsanitized Path Parameters","modified":"2026-05-13T13:52:30.530815Z","packages":[{"ecosystem":"npm","name":"i18next-locize-backend","purl":"pkg:npm/i18next-locize-backend","ranges":["<9.0.2"],"fixed":["9.0.2"]}]}],"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).
