Business Logic Vulnerability

A logic vulnerability refers to a design flaw at the business rule level of a program, rather than a technical error in the code implementation.

Automated scanners and fuzzing tools are usually based on known attack patterns (such as SQL injection and XSS signatures) and cannot understand whether an operation should be allowed in a business context, so they struggle to find logic vulnerabilities.

Features involving role switching, cross-organization access, and token passing are high-incidence zones for logic vulnerabilities; such problems are difficult for automated tools to discover, have a high severity level, and correspondingly pay higher bounties.

The discovery of high-value vulnerabilities (such as logic vulnerabilities, privilege bypasses, and business process flaws) still requires a deep human understanding of business logic that AI cannot replace.
