Prior to 4.0.2, attacker-controlled language or namespace values interpolated into a custom loadPath or addPath that begins directly with {{lng}} or {{ns}} can make colon-based input become an absolute URL or, in browsers, make a double-slash namespace become a protocol-relative URL. The resulting request can leave the intended origin and cause URL injection or server-side request forgery. The default /locales/{{lng}}/{{ns}}.json template and templates with a leading path or origin are not affected because the placeholder does not occupy the URL's structural beginning. This issue is fixed in version 4.0.2.","state":0,"publishedAt":"2026-10-06T15:17:17.173+00:00","modifiedAt":"2026-10-06T18:16:47.547+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://github.com/i18next/i18next-http-backend/commit/07e028862b25d0b9251bf3cafb92be2d35285f85","https://github.com/i18next/i18next-http-backend/releases/tag/v4.0.2","https://github.com/i18next/i18next-http-backend/security/advisories/GHSA-xvq9-wjp8-hwqf"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-105800","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-74","CWE-918"],"productCriteria":[],"sourceDates":{"published":"2026-10-06T15:17:17.173","lastModified":"2026-10-06T18:16:47.547"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
