The Most Common API Vulnerabilities

The Most Common API Vulnerabilities

Application Programming Interface (API) provides developers and website owners with source code from existing applications which can then be repurposed for their (the developer’s) specific needs and integrated into existing business and site functions to improve user experience.


In short, API has become essential for online business, and anything essential quickly becomes a target for malicious actors. 


If you are a developer or you are using APIs in various applications on your site, below are some of the most common API vulnerabilities, how they are targeted, and what you can do to help mitigate their potential damage. 


Code Injections


Code injections are a favorite way for malicious actors to commandeer an API and have it do all manner of things that you or your client won’t want them to. The most common code injections include SQL, XML, and RegEx, and API, and they send commands to applications to do things like share sensitive user data, passwords, and other authentication information, and plant malware and spyware on devices.

One of the best ways to make sure that your API is fortified against code injections is to perform manual tests, and particularly intensive query checks, to determine if and how someone with bad intentions might go about inserting malicious code into an application.
