5 API Vulnerabilities That Get Exploited by Criminals

Let’s give a look at API vulnerabilities by reading the API Security Top 10 published by the Open Web Application Security Project (OWASP).

It’s no secret that cyber security has become a leading priority for most organizations — especially those in industries that handle sensitive customer information. And as these businesses work towards building robust security strategies, it’s vital that they account for various threat vectors and vulnerabilities.

One area that requires significant scrutiny is API security. APIs, short for application programming interfaces, have become a common building block for digitally enabled organizations. They facilitate communication as well as critical business operations, and they also support important digital transformations. It’s no surprise then that the average number of APIs per company increased 221% in the last year.

Crafting an API security strategy is a complex task. APIs have unique threat implications that aren’t fully solved by web application firewalls or identity and access management solutions. The first step to getting it right is to understand what the common vulnerabilities are.

5 Common API Vulnerabilities Explained

In its API Security Top 10, the Open Web Application Security Project (OWASP) identifies the top ten threats to APIs. Below, we take a closer look at some of the most common.

1. Broken Object Level Authentication (BOLA)

APIs with broken object level authentication allow attackers to easily exploit API endpoints by manipulating the ID of an object sent within an API request. The result? BOLA authorization flaws can lead to unauthorized viewing, modification or destruction
