The Standard

Summary

Chainlink’s latestRoundData might return stale or incorrect results

Vulnerability Details

If there is a problem with Chainlink starting a new round and finding consensus on the new value for the oracle (e.g. Chainlink nodes abandon the oracle, chain congestion, vulnerability/attacks on the chainlink system) consumers of this contract may continue using outdated stale or incorrect data (if oracles are unable to submit no new round is started).

Impact

Recommendations

Add checks on the return data with proper revert messages if the price is stale or the round is uncomplete
