Security Score: Violation

Grade F

CRITICALLine 5

Unsanitized Dynamic SQL Concatenation ($queryRawUnsafe)

User-controlled input userId is concatenated directly into a raw SQL query string without escaping or parameter binding, allowing arbitrary SQL execution.

SEC-OWASP-SQLI-001CWE-89: SQL Injection

Autonomous AI Remediation Synthesizer

Refactored to use Prisma parameterized template literal ($queryRaw), which automatically escapes all embedded expressions and parameterizes the SQL statement.

Frequently Asked Questions

Everything you need to know about System Audit, local LLM execution, and repository privacy.

Traditional linters only look for style issues and simple syntax errors, while legacy SAST tools often produce thousands of noisy false positives without showing you how to fix them. System Audit pairs 14 deep static & AST engines (measuring cognitive complexity, OWASP vulnerabilities, Shannon entropy secrets, N+1 query loops, and Docker/K8s misconfigurations) with an Autonomous AI Synthesizer that generates ready-to-merge unified diff patches for each finding.
