PRD-44: Platform Security Hardening & Architecture Remediation

Version: 2.0 Status: Partially Complete — v2 Ralph task created Date: February 25, 2026 (Updated) Author: Claude Opus 4.5 (Original) / Claude Opus 4.6 (v2 Audit) Prerequisites: None Blocks: Go-live readiness

---

Audit Summary (Feb 25, 2026)

A full re-audit was performed against the current codebase. Of the original 45 user stories, 12 have been completed, 3 are partially addressed, and 30 remain open. Additionally, 4 new findings were discovered.

The completed items represent significant progress — the platform now has:

• Secure-by-default authentication (REQUIRE_AUTH=true)

• Rate limiting via slowapi (60/min default)

• Proper CORS with explicit origins (no wildcards)

• Security headers on all responses (X-Content-Type-Options, X-Frame-Options, CSP, HSTS)

• Mandatory GitHub webhook HMAC-SHA256 verification

• Workspace membership verification

• MIME type validation on file uploads

• Swagger/ReDoc disabled in production

• Browser-exposed API key removed

• Auto-admin domain logic removed

New Findings (Added to v2)

Finding	Severity	Description
Unauthenticated generated_images	CRITICAL	GET /api/generated-images/{image_id} has zero auth
Broken admin_prompts role check	HIGH	_assert_admin() allows ANY authenticated user
Missing admin check on system_settings	HIGH	Any auth user can modify platform settings
Audit service is a stub	MEDIUM	audit_service.py is 199 bytes with no implementation
No global body size limit	MEDIUM	Only doc upload has 50MB limit
No DB SSL enforcement	MEDIUM	sslmode not specified for production
Dev Docker runs as root	LOW	Development stage lacks non-root user

Remaining work captured in Ralph format

Original Introduction

A comprehensive architect review and API security audit of the Automatos AI Platform identified 3 critical, 7 high, 7 medium, and 5 low severity security vulnerabilities alongside 12 architectural issues. This PRD addresses all findings through focused, individually-implementable user stories organized into six phases.

The platform currently fails 8 of 10 OWASP API Security Top 10 categories. After remediation work, the platform now passes roughly 6 of 10 OWASP categories. Auth is enabled by default, most routers have authentication, SQL injection vectors are largely eliminated, and security headers/rate limiting are in place.

Remaining gaps: broken authorization (admin role checks), excessive data exposure (error messages), and dependency vulnerabilities.

---

Goals

• Achieve OWASP API Security Top 10 compliance across all endpoints Close remaining OWASP gaps (Broken Authorization, Excessive Data Exposure)

• Enforce authentication on 100% of mutation and data-access endpoints Fix remaining unauthenticated endpoint (generated_images)

• Eliminate all SQL injection vectors Fix remaining f-string SQL patterns

• Fix all runtime crashes (NameError, undefined references) Verify fixed

• Implement rate limiting, security headers, and proper CORS DONE

• Implement proper admin role enforcement across sensitive endpoints

• Sanitize error responses to stop leaking internal details

• Update outdated dependencies with known CVEs

• Implement functional audit logging

---

Non-Goals

• Secret rotation (deferred to go-live preparation)

• Full test suite creation (separate PRD)

• Frontend redesign or UX changes

• New feature development

• Performance optimization beyond fixing N+1 queries

• CI/CD pipeline changes

• Architecture decomposition (deferred — large scope, separate PRD)
