CVE-2021-41264
Good to know:
Date: November 12, 2021
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).
