AI code audit
The full source archive was read by our AI auditor against each check. It reads the code — it does not run it; running it is part 2.
| Check | What we found | Score | Result |
|---|---|---|---|
| Secrets & credentials | No committed API keys, passwords or connection strings with real credentials were detected. The appsettings.json ships with empty connection strings and placeholder SMTP values, which is correct. However, Security:RequireEmailConfirmation defaults to true while Email:Host is empty, which will break registration silently in production if not configured. | 92 | Warning |
| Dependency vulnerabilities | The project uses .NET 10 (ASP.NET Core) with NuGet packages managed through .csproj files. All 12 dependencies are pinned to specific versions with no wildcards. No known critical vulnerabilities detected in the declared packages. Minor version updates available for some packages (BCrypt.Net-Next, ClosedXML, QRCoder) but these are maintenance updates, not security patches. | 95 | Pass |
| Authorisation & access control | All admin routes require Administrator role and authentication. Mutating endpoints are properly guarded. Password hashing uses BCrypt. However, student profile and enrollment details lack ownership checks—any authenticated user can view another's profile by changing the userId parameter. Certificate verification is intentionally public. | 92 | Warning |
| Database access rules | All SQL is properly parameterised through ISqlExecutor with no string concatenation. Soft deletes are guarded against dependent records. The schema is complete and idempotent. However, several foreign key columns lack indexes, which will cause performance issues as data grows. | 95 | Pass |
| Code structure & duplication | Architecture follows clean layering (Domain → Application → Infrastructure → Web) with appropriate boundaries. Business logic is correctly isolated from controllers. However, there is moderate duplication in repository patterns, some magic strings scattered across files, and a few oversized service classes that could be split. | 78 | Warning |
| Build reproducibility | The solution builds cleanly with consistent .NET 10 references and proper project structure. Database scripts are idempotent and well-organized. Minor issues: HowToSetup.md is referenced but not included in the digest, appsettings.json has empty connection string requiring manual edit, and the setup order could be clearer about configuration before first run. | 92 | Pass |

What this report covers — and what it doesn't
- It covers version 1.0.0 exactly as the buyer downloads it: the source archive, the setup guide and the live demo on the dates above.
- It is not a penetration test, a performance or load test, or a legal review of third-party package licences.
- Scores are a point in time. Libraries age; a later version is audited again and gets its own report.
- Your setup matters. Hosting, configuration and changes made after purchase are outside this review.
- How the score is made: each AI check is scored 0–100 and weighted (security counts most). A listing needs 75 or more, no failing check, and the human review passed.
- Always try the live demo before buying, and ask the builder questions from the product page.
