Prior to version 2.6.4, i18next-fs-backend substitutes the lng and ns options directly into the configured loadPath / addPath templates and then read / write the resulting file from disk. The interpolation is unencoded and unvalidated, so a crafted lng or ns value — containing .., a path separator, a control character, a prototype key, or simply an unexpectedly long string — allows an attacker who can influence either value to read or overwrite files outside the intended locale directory. When lng / ns are derived from untrusted input (request-scoped i18next instances behind an HTTP layer such as i18next-http-middleware, or any framework that lets the end user pick the language via query string, cookie, or header), a single request such as ?lng=../../../../etc/passwd causes the backend to attempt to read that path. This issue has been patched in version 2.6.4.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-41693","reference_id":"","reference_type":"","scores":[{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.18243","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.18088","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.18269","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00057","scoring_system":"epss","scoring_elements":"0.18249","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-41693"},{"reference_url":"https://github.com/i18next/i18next-fs-backend","reference_id":"","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/i18next/i18next-fs-backend"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41693","reference_id":"","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41693"},{"reference_url":"https://github.com/advisories/GHSA-8847-338w-5hcj","reference_id":"GHSA-8847-338w-5hcj","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-8847-338w-5hcj"},{"reference_url":"https://github.com/i18next/i18next-fs-backend/security/advisories/GHSA-8847-338w-5hcj","reference_id":"GHSA-8847-338w-5hcj","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-13T17:16:51Z/"}],"url":"https://github.com/i18next/i18next-fs-backend/security/advisories/GHSA-8847-338w-5hcj"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/374115?format=json","purl":"pkg:npm/i18next-fs-backend@2.6.4","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/i18next-fs-backend@2.6.4"}],"aliases":["CVE-2026-41693","GHSA-8847-338w-5hcj"],"risk_score":4.0,"exploitability":"0.5","weighted_severity":"8.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-77hd-4vqt-3fhu"}],"fixing_vulnerabilities":[],"risk_score":"4.0","resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/i18next-fs-backend@2.1.4"}
