Q1Domain Verified
In the context of REST API security testing as taught in "The Complete REST API Hacking Course 2026," which vulnerability is most likely to be exploited through excessive or malformed JSON payloads sent to an API endpoint designed to process complex data structures?
XML External Entity (XXE) injection, assuming the API internally parses JSON as XML.
Denial of Service (DoS) or Resource Exhaustion, by overwhelming the API's parsing or processing logic.
Cross-Site Scripting (XSS), by injecting script tags into JSON values.
SQL Injection, by crafting malicious SQL queries within the JSON.
Q2Domain Verified
According to the principles of REST API penetration testing, when assessing authorization for an authenticated user with different roles, which technique is most effective for verifying if an unauthorized role can access privileged resources?
Sending requests to privileged endpoints with valid credentials of the unauthorized user and observing the response codes and content.
Using automated tools to fuzz all parameters and headers for common authorization bypass patterns.
Modifying the `Authorization` header to impersonate a user from the privileged role.
Attempting to access all available endpoints with the unauthorized user's credentials.
Q3Domain Verified
In the advanced stages of REST API penetration testing, if an API endpoint utilizes JWT (JSON Web Tokens) for authentication and authorization, what is a common and critical vulnerability to investigate if the token's signature verification is improperly implemented?
Cross-Site Request Forgery (CSRF) on JWT endpoints.
Insecure Direct Object Reference (IDOR) within JWT claims.
Token forgery, allowing an attacker to create valid tokens with arbitrary claims.
Rate limiting bypass through token manipulation.
