Improper Initialization in OpenZeppelin
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @openzeppelin/contracts | < 4.4.1 | 4.4.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
