GHSA-F4JP-RW7W-CCWG gettext-converter: Prototype pollution in js2i18next() via crafted translation keys

Impact js2i18next is vulnerable to prototype pollution. When converting translations, it splits nested keys on the key separator default and uses each segment as a dynamic object key while building the output object. A key whose segment is proto e.g. protogcPolluted causes the converter to resolv...
