What is the OWASP Top 10?
The Open Worldwide Application Security Project (OWASP) Top 10 is the de facto standard for web application security risk. Updated periodically to reflect real-world attack data, it guides developers and security teams on the most critical vulnerabilities to address.
What Changed in 2025
**A01 - Broken Access Control** remains at the top. Over 94% of applications tested had some form of access control failure.
**A02 - Cryptographic Failures** (formerly Sensitive Data Exposure) reflects the growing importance of encryption in transit and at rest.
**A03 - Injection** — SQL, NoSQL, OS, and LDAP injection remain critical concerns, now expanding to include prompt injection against LLM-based applications.
Why It Matters
Every developer who understands the OWASP Top 10 can prevent the majority of common attacks. At Shuraya Labs, we cover all 10 categories in depth in our Web Application Penetration Testing course.
