Improper Initialization in OpenZeppelin
Quick fix
GHSA-88g8-f5mf-f5rj — @openzeppelin/contracts: upgrade to the fixed version with the command below.
npm install @openzeppelin/contracts@4.4.1Details
In OpenZeppelin <=v4.4.0, initializer functions that are invoked separate from contract creation (the most prominent example being minimal proxies) may be reentered if they make an untrusted non-view external call. Once an initializer has finished running it can never be re-executed. However, an exception put in place to support multiple inheritance made reentrancy possible, breaking the expectation that there is a single execution.
