First Flight #5: Santa's List

Summary

The events CheckedOnce and CheckedTwice are missing the indexed keyword for their parameters, especially `address person". This can result in inefficient event filtering and querying, as well as potential limitations in the ability to track and analyze events.

Vulnerability Details

The events CheckedOnce and CheckedTwice are missing the indexed keyword for their parameters. When an event parameter is marked as indexed, it allows for efficient filtering and querying of events based on that parameter. Without the indexed keyword, it will be complicated to find if a people has been checked by Santa.

Impact

The missing event indexing can have the following impacts:

• Inefficient event filtering and querying: Without the indexed keyword, filtering and querying events based on the parameters of CheckedOnce and CheckedTwice will not be as efficient as it could be. This can result in increased computational costs and slower performance.

• Limitations in event analysis: The absence of event indexing can limit the ability to track and analyze the events accurately. It may hinder the ability to extract meaningful insights from the events and perform comprehensive event analysis.

Recommendations

To address the missing event indexing, it is recommended to modify the event declarations as follows:

By adding the indexed keyword to the person parameter, event filtering and querying will be more efficient, leading to improved performance. Additionally, it will enable better event analysis and tracking capabilities.
