Authorization Logic Flaw
An authorization logic flaw is a broader category of security errors where the rules defining what a user is allowed to do are fundamentally broken or improperly designed. Unlike simple missing checks, these flaws often involve complex interactions where the protocol's state machine reaches an unauthorized condition.
For example, a system might incorrectly calculate a user's permissions based on flawed internal state variables. If the underlying logic that dictates authorization is flawed, no amount of standard modifiers can secure the system.
These errors often require deep architectural analysis to identify and remediate.
