CWE-758: Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

Class

The product uses an API function, data structure, or other entity in a way that relies on properties that are not always guaranteed to hold for that entity.

This can lead to resultant weaknesses when the required properties change, such as when the product is ported to a different platform or if an interaction error (CWE-435) occurs.

Consequences

Other: Reduce Maintainability, Unexpected State, Quality Degradation
