- "Developers working for startup OpenZeppelin found vulnerabilities in Move. “The vulnerability in the Move IR compiler allows malicious actors to introduce executable code to their smart contracts disguised as inline comments,” OpenZeppelin’s CEO Demian Brener told CoinDesk. Brener said the code was disclosed to Libra Aug. 6, with the Libra team evaluating and fixing the bug over the following month. As of Sept. 4, the patch was reviewed and confirmed to be fixed by OpenZeppelin."
