Vulnerable REST API with OWASP top 10 vulnerabilities for security testing.
VAmPI is a vulnerable API made with Flask and it includes vulnerabilities from the OWASP top 10 vulnerabilities for APIs. It was created as I wanted a vulnerable API to evaluate the efficiency of tools used to detect security issues in APIs. It includes a switch on/off to allow the API to be vulnerable or not while testing. This allows to cover better the cases for false positives/negatives. VAmPI can also be used for learning/teaching purposes. You can find a bit more details about the vulnerabilities in erev0s.com.
