      "value": "OpenZeppelin Contracts is a library for smart contract development. In affected versions upgradeable contracts using `UUPSUpgradeable` may be vulnerable to an attack affecting uninitialized implementation contracts. A fix is included in version 4.3.2 of `@openzeppelin/contracts` and `@openzeppelin/contracts-upgradeable`. For users unable to upgrade; initialize implementation contracts using `UUPSUpgradeable` by invoking the initializer function (usually called `initialize`). An example is provided [in the forum](https://forum.openzeppelin.com/t/security-advisory-initialize-uups-implementation-contracts/15301)."

En las versiones afectadas, los contratos actualizables que usan \"UUPSUpgradeable\" pueden ser vulnerables a un ataque que afecta a los contratos de implementaci\u00f3n no inicializada. Se incluye una correcci\u00f3n en la versi\u00f3n 4.3.2 de \"@openzeppelin/contracts\" y \"@openzeppelin/contracts-upgradeable\". Para usuarios que no puedan actualizar; inicialice los contratos de implementaci\u00f3n usando \"UUPSUpgradeable\" al invocar la funci\u00f3n inicializadora (normalmente llamada \"initialize\"). Se proporciona un ejemplo [en el foro](https://forum.openzeppelin.com/t/security-advisory-initialize-uups-implementation-contracts/15301)"
