OWASP API Top 10 2023


It looks like you’ve listed a set of potential security vulnerabilities or issues related to APIs in the context of the year 2023. These appear to be issues that developers and security professionals should be aware of and take measures to address to ensure the security of their APIs and the applications that use them. Here’s a brief description of each issue:

  1. Broken Object Level Authorization (API1:2023): This vulnerability indicates that the application doesn’t properly enforce access controls, allowing unauthorized users to manipulate objects or data they shouldn’t have access to.
  2. Broken Authentication (API2:2023): This vulnerability suggests that there are weaknesses in the authentication process, making it possible for attackers to gain unauthorized access to user accounts or system resources.
  3. Broken Object Property Level Authorization (API3:2023): Similar to issue #1, this vulnerability pertains to the improper handling of authorization at the object property level, allowing unauthorized access to specific properties of objects.
  4. Unrestricted Resource Consumption (API4:2023): This issue implies that the API does not have adequate rate limiting or resource management, making it susceptible to abuse, such as denial-of-service attacks or resource exhaustion.
  5. Broken Function Level Authorization (API5:2023): This vulnerability suggests that the API’s functions or endpoints are not adequately protected, allowing unauthorized users to execute privileged functions.
  6. Unrestricted Access to Sensitive Business Flows (API6:2023): This issue indicates that sensitive business processes or flows within the application are not properly secured, potentially exposing critical operations to unauthorized access or manipulation.
  7. Server Side Request Forgery (API7:2023): This vulnerability implies that the API allows attackers to make requests to internal resources or third-party systems, potentially leading to data exposure or other security risks.
  8. Security Misconfiguration (API8:2023): This issue signifies that the API or its underlying infrastructure has misconfigurations that can be exploited by attackers to gain unauthorized access or perform other malicious actions.
  9. Improper Inventory Management (API9:2023): This vulnerability suggests that the API doesn’t manage its resources or inventory properly, potentially leading to inefficiencies or security risks.
  10. Unsafe Consumption of APIs (API10:2023): This issue implies that the API consumes other APIs in an unsafe manner, possibly leading to data exposure, injection attacks, or other security problems.

To mitigate these vulnerabilities, developers and organizations should follow best practices for API security, including proper authentication and authorization mechanisms, input validation, rate limiting, and regular security testing and auditing of their APIs. Staying up-to-date with security trends and patches is also crucial in maintaining a secure API ecosystem.
