Eggstravaganza

Summary

The smart contracts use floating pragma versions, which can lead to the unintentional use of outdated or incompatible Solidity compiler versions, potentially introducing bugs or security vulnerabilities.

Vulnerability Details

Floating pragma statements (e.g., ^0.8.0) specify a range of acceptable compiler versions rather than locking to a specific version. This can result in:

• Deployment with compiler versions that introduce breaking changes or semantic differences.

• Exposure to experimental features that haven't been thoroughly tested.

• Difficulties in reproducing builds, making debugging and auditing more complex.

Strict versioning ensures consistency across environments and avoids surprises caused by compiler updates.

Impact

The use of floating pragmas can compromise contract stability, security, and reproducibility.

Tools Used

• Manual Code Review

Recommendations

Use an exact compiler version (e.g., pragma solidity 0.8.23;) to ensure predictable and secure contract behavior.
