Pervaxis.Genesis.Sanitization

Server-side input sanitization module for the Pervaxis Genesis platform. Prevents stored/reflected XSS at the service layer using whitelist-based HTML sanitization.

Features

  • ISanitizer interface — StripAll, SanitizeHtml, and profile-based Sanitize methods
  • Three built-in profiles — PlainText, SafeHtml, Markdown
  • Custom profiles — Define additional profiles via configuration
  • [Sanitize] attribute — Declarative sanitization on DTO string properties at model binding time
  • FluentValidation extensions — .Sanitized() (transform) and .MustBeSanitized() (reject)
  • Global middleware — Optional auto-sanitization of POST/PUT/PATCH request bodies (off by default)
  • Observability — Metrics (operations, threats detected, duration) and structured logging

Quick Start

// Program.cs
builder.Services.AddGenesisSanitization(builder.Configuration.GetSection("Genesis:Sanitization"));
app.UseGenesisSanitization();

// appsettings.json
{
  "Genesis": {
    "Sanitization": {
      "DefaultProfile": "PlainText",
      "AllowCustomProfiles": true,
      "MaxInputLength": 1000000,
      "EnableMiddleware": false
    }
  }
}

Usage

Explicit in service layer

public class CommentService
{
    private readonly ISanitizer _sanitizer;

    public async Task<Comment> CreateAsync(CreateCommentRequest request)
    {
        var safeContent = _sanitizer.SanitizeHtml(request.Body);
        // ... store safeContent
    }
}

Declarative on DTO

public record CreateCommentRequest
{
    [Sanitize(Profile = "SafeHtml")]
    public required string Body { get; init; }
}

FluentValidation

public class CreateCommentValidator : AbstractValidator<CreateCommentRequest>
{
    public CreateCommentValidator(ISanitizer sanitizer)
    {
        RuleFor(x => x.Body)
            .Sanitized(sanitizer, "SafeHtml")
            .NotEmpty();
    }
}

Implementation

Uses HtmlSanitizer (Ganss.Xss) — a mature, battle-tested .NET library with whitelist-based sanitization that handles edge cases including nested encoding, unicode tricks, and attribute injection.
