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.","state":0,"publishedAt":"2026-05-08T15:41:14.065+00:00","modifiedAt":"2026-05-08T16:06:11.177+00:00","affected":[{"ecosystem":"Vendor product","name":"i18next-locize-backend","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"locize\",\n                    \"product\": \"i18next-locize-backend\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 9.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/locize/i18next-locize-backend/security/advisories/GHSA-mgcp-mfp8-3q45"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-41885","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-41885","identifiers":["CVE-2026-41885"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
