Oracle Manipulation Risk (Price Manipulation)

bareli

Summary

The function willPositionCollateralBeSufficient relies on prices.shortTokenPrice.min.toInt256() for collateral calculations. If an attacker can manipulate the oracle or TWAP pricing, they may artificially inflate collateral value, bypassing margin requirements.

Vulnerability Details

function willPositionCollateralBeSufficient(
IDataStore dataStore,
MarketProps memory market,
MarketPrices memory prices,
bool isLong,
WillPositionCollateralBeSufficientValues memory values
) external view returns (bool, int256) {
PriceProps memory collateralTokenPrice = prices.shortTokenPrice;
​
@>>int256 remainingCollateralUsd = values.positionCollateralAmount.toInt256() * collateralTokenPrice.min.toInt256();

Impact

A trader could open positions with artificially low collateral requirements.

Attackers might manipulate prices to avoid liquidation or force wrongful liquidations.
