Cross-Function Reentrancy
Cross-Function Reentrancy occurs when an attacker exploits shared state variables across different functions within the same smart contract. Even if a single function is protected by a reentrancy guard, a different function that accesses the same state might remain vulnerable.
By interleaving calls between these functions, an attacker can manipulate the contract state in an unexpected order. This vulnerability underscores the need for global, contract-wide state protection rather than just function-level locks.
It is a more subtle form of the standard reentrancy attack. Developers must ensure that all state changes are atomic and consistent across the entire contract lifecycle.
