CWE-407

Low likelihood

Inefficient Algorithmic Complexity

Parent: CWE-405 - Asymmetric Resource Consumption (Amplification)

An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
