Understanding the Threat of Read- Only Reentrancy Attacks on YourSmart Contracts
Read-only reentrancy refers to a situation where a view function is reentered, typically without any protective measures, as it doesn’t modify the contract’s state. However, if the contract’s state is inconsistent, this could lead to incorrect values being reported. Additionally, this vulnerability can be exploited by attackers to deceive other protocols that rely on return…

A Vulnerability present in the Vyper smart contract language allows for the exploitation of multiple issues.
Certain Curve factory pools, such as those managed by AlchemixFi and JPEG’d, fell victim to exploitation due to a critical flaw in the Vyper language. Vyper is a smart contract programming language that shares similarities with Solidity. Preliminary findings indicate that certain versions of the Vyper compiler failed to adequately implement a re-entrancy guard, thereby…
