Medium Risk

gettext-converterTL;DR
js2i18next() was vulnerable to prototype pollution when translation keys included dangerous segments like __proto__, constructor, or prototype. An attacker could craft translation keys that modified Object.prototype during JSON generation. The fix adds explicit detection of these unsafe key segments and skips/removes them so they cannot be used as dynamic object keys.
