CVE-2021-39168 · TimelockController vulnerability in OpenZeppelin Contracts
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
OpenZepplin is a library for smart contract development. In affected versions a vulnerability in TimelockController allowed an actor with the executor role to escalate privileges. Further details about the vulnerability will be disclosed at a later date. As a workaround revoke the executor role from accounts not strictly under the team's control. We recommend revoking all executors that are not also proposers. When applying this mitigation, ensure there is at least one proposer and executor remaining.
