Authentication and Authorization Defects in AI-Generated Code The Systemic Nature of Auth Vulnerabilities A 2025 study by Databricks revealed: "AI-generated authentication systems frequently incorporate outdated patterns and fail to implement modern security practices, creating what we call 'authentication debt' in codebases." The Statistics The research found that: - 73% of AI-generated authentication code lacked proper session management - 81% stored passwords insecurely (MD5, SHA1, or plaintext) These aren't edge cases—they're the norm in AI-generated authentication code. 1.2.1 Insecure Pa…
