Summary

Vulnerability Details

This vulnerability is due to the lack of range checks for the 'id' parameter in the 'increaseCollateral', 'decreaseCollateral', and 'combineShorts' functions. The 'id' parameter is used to index into the 'shortRecords' mapping, but there are no checks to ensure that the 'id' is within a valid range. This could potentially allow an attacker to manipulate or access arbitrary data in the 'shortRecords' mapping by providing an 'id' that is outside the expected range.

Impact

This could lead to unexpected behavior or potential loss of funds

Tools Used

Recommendations

To resolve this issue, you should add a function that checks if the provided ID is within the acceptable range. This function should be called within the increaseCollateral, decreaseCollateral, and combineShorts functions to validate the ID before any other operations are performed. Here is an example of how you could implement this:

This will ensure that only valid IDs are processed, preventing potential errors or issues.
