Distorting the price feed a protocol relies on, so that the protocol values collateral or debt incorrectly and can be exploited at that valuation.
Why it matters
Protocols reading a spot price from a single venue are most exposed, because that price can be moved within one transaction. Time-weighted averages and multiple independent sources raise the cost of the attack.
What you can check
Protocol documentation should name the price source and say whether it is a spot reading from a single venue or a time-weighted figure across several. A price taken from a pool that the same transaction can move is the shape that recurs.
