SCA: security update for i18next-http-middleware (GHSA-c3h8-g69v-pjrg)

high Tenable Self-Hosted Container Security Plugin ID 440745

Description

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

- i18next-http-middleware is a middleware to be used with Node.js web frameworks like express or Fastify and
also for Deno. Prior to version 3.9.3, i18next-http-middleware wrote user-controlled language values into
the Content-Language response header after passing them through utils.escape(), which is an HTML-entity
encoder that does not strip carriage return, line feed, or other control characters. When the application
used an older i18next (< 19.5.0) that still exercised the backward-compatibility fallback at
LanguageDetector.js:100 or otherwise produced a raw detected value, CRLF sequences in the attacker-
controlled lng parameter reached res.setHeader('Content-Language', ...) verbatim. This issue has been
patched in version 3.9.3. (CVE-2026-41683)

Solution

Update the i18next-http-middleware library and its related packages to version 3.9.3 or later.
