Summary

Inadequate event emission for critical operations within a smart contract can lead to significant issues in transparency, accountability, and monitoring. Events are essential for logging significant actions and changes within a contract, facilitating debugging, audits, and external integrations.

Vulnerability Details

The contract does not consistently emit events for critical operations such as module installation, uninstallation, and contract upgrades. Proper event emission is essential for transparency and monitoring of contract activities.

Impact

• Lack of visibility into critical operations, making it difficult to track and audit changes.

• Potential issues with off-chain services and monitoring tools that rely on events to detect and respond to important contract activities.

Tools Used

Manual Review

Recommendations

• Emit events for all critical operations, including module installations, uninstallations, and contract upgrades.

• Ensure that event data includes sufficient information to identify the nature and context of the operation.

• Regularly review and update event emission logic to cover all critical functions and changes.
