CVE-2023-34234
MEDIUM5.3EPSS 0.11%OpenZeppelin Contracts's governor proposal creation may be blocked by frontrunning
描述
### Impact By frontrunning the creation of a proposal, an attacker can become the proposer and gain the ability to cancel it. The attacker can do this repeatedly to try to prevent a proposal from being proposed at all. This impacts the `Governor` contract in v4.9.0 only, and the `GovernorCompatibilityBravo` contract since v4.3.0. ### Patches The problem has been patched in 4.9.1 by introducing opt-in frontrunning protection. ### Workarounds Submit the proposal creation transaction to an endpoint with frontrunning protection. ### Credit Reported by Lior Abadi and Joaquin Pereyra from Coinspect. ### References https://www.coinspect.com/openzeppelin-governor-dos/
