What Security Vulnerability Is Associated with “Reentrancy” in Smart Contracts?
Reentrancy is a critical vulnerability where an external contract call can recursively call back into the original contract before the first execution is complete. This allows the attacker to repeatedly drain funds from the contract.
The most famous example is the DAO hack, which exploited this flaw.
