The former category for XML External Entities (XXE) is now part of this category. With more shifts into highly configurable software, it’s not surprising to see this category move up.

A05:2021-Security Misconfiguration moves up from #6 in the previous edition 90% of applications were tested for some form of misconfiguration.

If we genuinely want to “move left” as an industry, it calls for more use of threat modeling, secure design patterns and principles, and reference architectures.

A04:2021-Insecure Design is a new category for 2021, with a focus on risks related to design flaws.Cross-site Scripting is now part of this category in this edition. 94% of the applications were tested for some form of injection, and the 33 CWEs mapped into this category have the second most occurrences in applications. A03:2021-Injection slides down to the third position.The renewed focus here is on failures related to cryptography which often leads to sensitive data exposure or system compromise. A02:2021-Cryptographic Failures shifts up one position to #2, previously known as Sensitive Data Exposure, which was broad symptom rather than a root cause.The 34 Common Weakness Enumerations (CWEs) mapped to Broken Access Control had more occurrences in applications than any other category. A01:2021-Broken Access Control moves up from the fifth position 94% of applications were tested for some form of broken access control.There are three new categories, four categories with naming and scoping changes, and some consolidation in the Top.

Using the OWASP Top 10 is perhaps the most effective first step towards changing the software development culture within your organization into one that produces more secure code. Globally recognized by developers as the first step towards more secure coding.Ĭompanies should adopt this document and start the process of ensuring that their web applications minimize these risks. It represents a broad consensus about the most critical security risks to web applications. The OWASP Top 10 is a standard awareness document for developers and web application security.
