# CVE-2017-16010: i18next is a language translation framework.

- Also known as: GHSA-CMH5-QC8W-XVCQ
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 3.4.4
- Published: 2018-05-29 · Updated: 2024-09-16

## Affected

- HackerOne i18next node module: \>=2.0.0 \<=3.4.3
- i18next (npm): from 2.0.0, fixed in 3.4.4

## Description

i18next is a language translation framework. When using the .init method, passing interpolation options without passing an escapeValue will default to undefined rather than the assumed true. This can result in a cross-site scripting vulnerability because user input is assumed to be escaped, but is not. This vulnerability affects i18next 2.0.0 and later.

## What to do
