- Learn about the OWASP organization, the history behind the API Security Top 10, and what’s changed between 2019 and 2023.
- API1:2023 – Broken Object Level Authorization: BOLA is still the leading vulnerability that plagues APIs. When data objects do not have sufficient access controls in place, resources can be accessed by unauthorized users.
- API2:2023 – Broken Authentication: Broken Authentication contains all vulnerabilities associated with authentication. This section includes weak passwords, JSON Web Token (JWT) misconfigurations, and insecure lockout mechanisms.
- API3:2023 – Broken Object Property Level Authorization: BOPLA is the combination of Excessive Data Exposure and Mass Assignment. An application should have sufficient access controls to prevent a user from altering sensitive data object properties.
- API4:2023 – Unrestricted Resource Consumption: APIs have technical and financial costs per request. If an API does not have sufficient controls in place then there will be a negative impact on the API provider.
- API5:2023 – Broken Function Level Authorization: This vulnerability is present if there are insufficient access controls in place between different user groups to perform sensitive actions.
- API6:2023 – Unrestricted Access to Sensitive Business Flows: Unrestricted Access to Sensitive Business Flows represents the risk of an attacker being able to identify and exploit API-driven workflows.
- API7:2023 – Server Side Request Forgery: Server Side Request Forgery is a vulnerability that takes place when a user is able to control the remote resources retrieved by an application.
- API8:2023 – Security Misconfiguration: Security Misconfiguration represents a catch-all for many vulnerabilities related to the systems that host APIs.
- API9:2023 – Improper Inventory Management: Improper Inventory Management represents the risks involved with exposing non-production and unsupported API versions.
- API10:2023 – Unsafe Consumption of APIs: Unsafe Consumption of APIs is the only item on the top ten list that focuses less on the risks of being an API provider and more on the API consumer.
- This module examines key threats outside the Top 10, including, injections, file upload vulnerabilities, business logic vulnerabilities, and logging and monitoring.
