A01:2025 – CWE-65 Explained | Improper Authorization (Release Candidate)

CWE-65 (Improper Authorization) is a core weakness associated with
A01:2025 – Broken Access Control in the OWASP Top 10: 2025 Release Candidate.

This weakness occurs when an application fails to correctly verify whether an authenticated user is allowed to perform a specific action or access a specific resource, resulting in unauthorized operations despite valid authentication.

📌 What you’ll learn in this video:

🔹 What CWE-65 (Improper Authorization) really means
🔹 Difference between authentication vs authorization failures
🔹 How CWE-65 leads directly to Broken Access Control (A01:2025)
🔹 Real-world examples (horizontal & vertical privilege abuse)
🔹 Business, security, and compliance impact
🔹 Secure design and prevention techniques

🧠 Why CWE-65 matters under A01:2025:

Allows users to perform actions beyond their role

Enables privilege escalation and data manipulation

Common in APIs, admin panels, and workflow actions

Often exploited even when authentication is strong

Results in major audit, regulatory, and governance failures

🛡️ Prevention & Mitigation (High Level):

✔ Enforce server-side authorization checks for every action
✔ Implement role-based / attribute-based access control (RBAC/ABAC)
✔ Never rely on client-side checks
✔ Validate authorization after authentication, before execution
✔ Regularly test authorization logic in VAPT & code reviews

🎯 Who should watch this video:

✔ Application & API Developers
✔ SOC Analysts & Security Engineers
✔ VAPT & Penetration Testers
✔ GRC & Compliance Professionals
✔ CISOs & Risk Owners
✔ Cybersecurity learners

If you work with:
✔ OWASP Top 10
✔ Secure application design
✔ VAPT & pentest reports
✔ ISO/IEC 27001
✔ SOC 2
✔ SEBI CSCRF

…this video will help you understand CWE-65 as the most fundamental access-control failure in real systems.

📌 Watch till the end to see why most access control bugs are authorization failures—not authentication issues.
