      "value": "RSSHub is an open source, easy to use, and extensible RSS feed generator. In RSSHub before version 7f1c430 (non-semantic versioning) there is a risk of code injection. Some routes use `eval` or `Function constructor`, which may be injected by the target site with unsafe code, causing server-side security issues The fix in version 7f1c430 is to temporarily remove the problematic route and added a `no-new-func` rule to eslint."

En RSSHub versiones anteriores a 7f1c430 (versionado no sem\u00e1ntico) se presenta el riesgo de inyecci\u00f3n de c\u00f3digo. Algunas rutas usan \"eval\" o \"Function constructor\", que pueden ser inyectadas por el sitio objetivo con c\u00f3digo no seguro, causando problemas de seguridad en el lado del servidor. La correcci\u00f3n en la versi\u00f3n 7f1c430 es eliminar temporalmente la ruta problem\u00e1tica y agregar una regla \"no-new-func\" para eslint"
