Oracles serve as bridges between external data sources and the blockchain. However, the integrity of the data they provide can be compromised by errors in data feeds, manipulation by attackers, or even technical malfunctions.
Sudden, unrealistic spikes or drops in price data can occur, which do not accurately reflect market conditions.
If an attacker can influence the oracle, either directly by tampering with the data source or indirectly through market manipulation, they might feed incorrect prices to the smart contract.
