GitHub Vulnerability Alerts

GHSA-9c22-pwxw-p6hx

Impact

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 in the scenario described above, breaking the expectation that there is a single execution.

Note that upgradeable proxies are commonly initialized together with contract creation, where reentrancy is not feasible, so the impact of this issue is believed to be minor.

Patches

A fix is included in the version v4.4.1 of @openzeppelin/contracts and @openzeppelin/contracts-upgradeable.

Workarounds

Avoid untrusted external calls during initialization.

Impact

The GovernorCompatibilityBravo module may lead to the creation of governance proposals that execute function calls with incorrect arguments due to bad ABI encoding. This happens if the proposal is created using explicit function signatures, e.g. a proposal to invoke the function foo(uint256) is created as propose([target], [0], ["foo(uint256)"], ["0x00..01"]). If the function selector is provided as part of the encoded proposal data the issue is not present, e.g. the same proposal is created as propose([target], [0], ["0x2fbebd3800..01"]), where 2fbebd38 is the function selector.

We've assessed the instances of this contract found on chain, and did not find any occurrence of this bug in the past. Proposal creation through Tally or OpenZeppelin Defender is not affected. The core Governor contract on its own is not affected.

Patches

A fix is included in version v4.4.2 of @openzeppelin/contracts and @openzeppelin/contracts-upgradeable.

Workarounds

Do not create proposals using explicit function signatures. Instead, use the propose function without the signatures argument, and create the proposal using the fully ABI-encoded function call including the function selector in the calldatas argument as explained above.
