Description:

Using a strict version of solidity ensures locking the version ensures that contracts are not deployed with a different version of solidity than they were tested with. A wide version might cause unintended results, unexpected behavior or security risks if future versions introduce changes or bugs. Also, using the latest solidity version is adviceable.

Impact:

• Compiler Changes: Can cause unexpected bugs due to differences in compiler behavior.

• Security Risks: This may expose the contract to known vulnerabilities in older compiler versions.

• Inconsistent Behavior: This leads to unpredictable contract behavior across different environments.

Manual Review

Recommended Mitigation:

Use a specific version of Solidity and the latest version of solidity instead of a wide version in your contracts. For example, instead of pragma solidity ^0.8.25;, use pragma solidity 0.8.25;
