SCA: security update for i18next-fs-backend (GHSA-8847-338w-5hcj)

high Tenable Self-Hosted Container Security Plugin ID 440727

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - i18next-fs-backend is a backend layer for i18next using in Node.js and for Deno to load translations from
 the filesystem. 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. (CVE-2026-41693)

Solution

Update the i18next-fs-backend library and its related packages to version 2.6.4 or later.
