Vulnerability Database
Deep dives into 29 common vulnerabilities found in AI-built web applications. Learn how to identify and fix security issues before attackers find them.
Understanding Web Application Vulnerabilities
Web application vulnerabilities are security flaws that attackers can exploit to access data, compromise systems, or disrupt services. In AI-generated applications, these vulnerabilities are particularly prevalent because AI coding tools prioritize delivering functional code quickly rather than implementing comprehensive security controls.
Security research from organizations like OWASP, Stanford University, and independent security firms has documented that approximately 80% of AI-built applications contain at least one exploitable vulnerability. Common issues include exposed credentials, misconfigured database access controls, missing authentication checks, and absent security headers.
Each vulnerability in this database includes a detailed explanation of what causes it, how attackers exploit it, and step-by-step guidance for fixing it. Understanding these vulnerabilities helps you recognize risky patterns in your own code and implement effective protections.
Vulnerabilities are categorized by severity based on their potential impact. Critical vulnerabilities can lead to complete system compromise or massive data breaches. High-severity issues allow significant unauthorized access. Medium-severity findings weaken your security posture but may require additional conditions to exploit.
Critical & High Severity
These vulnerabilities require immediate attention. They include exposed API keys that grant access to your services, database misconfigurations that leak user data, and authentication bypasses that allow unauthorized access. Attackers actively scan for these issues and can exploit them within hours of discovery.
Medium Severity
While not immediately critical, these vulnerabilities weaken your application's security posture. Missing security headers, weak session management, and information disclosure issues fall into this category. They often serve as stepping stones for more serious attacks.
