I discovered a SQL injection vulnerability in a practice web application that allowed me to bypass the login system and access the entire user database without any credentials. By inserting a simple payload into the username field, I successfully logged in as the first user in the database and extracted sensitive information including usernames, password hashes, and user email addresses. This finding was documented in a detailed report with proof-of-concept screenshots, risk analysis showing potential data breach impact, and step-by-step remediation guidance including parameterized queries and input validation. This assessment demonstrates my ability to find critical database vulnerabilities that could expose thousands of customer records.
