## Data Aggregation Vulnerabilities

Data aggregation vulnerabilities arise when a protocol relies on a single or centralized method to collect and average data from various sources. If the aggregation logic is flawed or the central aggregator is compromised, the entire system is at risk.

For example, if a protocol takes the median price from five exchanges but one exchange is easily manipulated, the median can be skewed. Attackers exploit these vulnerabilities by focusing their efforts on the weakest link in the aggregation chain.

They may also attempt to influence the timing or the weight given to certain data sources. Secure aggregation requires more than just taking an average; it involves outlier detection, weight adjustment based on liquidity, and cryptographic verification of the data sources.

Protocols must ensure that their aggregation logic is resistant to manipulation even when some sources are compromised. This is a complex engineering challenge that is central to the reliability of DeFi.

As protocols grow in complexity, the methods for aggregating data must become increasingly sophisticated to prevent exploitation. The goal is to create a robust data feed that remains accurate even under adversarial conditions.
