| ID | Severity | Summary | Affected versions | Published | Source |
|---|---|---|---|---|---|
| GHSA-f4jp-rw7w-ccwg | Moderate | 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. `__proto__##gcPolluted`) causes the converter to resolve `Object.prototype` as the nested write target and assign the translated value onto it, polluting `Object.prototype` for the whole runtime. Any application that converts translation data (PO / i18next JS objects) originating from an untrusted or user-controlled source |
