Details

Impact

This vulnerability affects all accounts (vanilla and ethereum flavors) in the v0.2.0 release of OpenZeppelin Contracts for Cairo, which are not whitelisted on StarkNet mainnet, so only goerli deployments of v0.2.0 accounts are affected.

This faulty behavior is not observed in StarkNet's testing framework, so don't rely on it passing to detect this issue on custom accounts.

Patches

This bug has been patched in v0.2.1.
