I now have comprehensive information. Let me compile my findings into a detailed OSINT report:\n\n## OSINT Analysis: josie.health API Information Leakage to Unauthenticated Users\n\nBased on my thorough code review of the josie.health API service, I've identified several areas where information is exposed to unauthenticated users:\n\n### 1. PUBLIC ENDPOINTS & UNAUTHENTICATED ROUTES\n\nThe API has intentionally unauthenticated endpoints (lines 103-118 in router.cr):\n\n**Routes that bypass authentication:**\n- `/health` - Health check endpoint\n- `/v1/` and `/v1` - API root\n- `/v1/substances` - Full substance database list\n- `/v1/substances/{name}/...` - All substance information (dosage, onset, duration, effects, aftereffects)\n- `/v1/interactions/{substance1}/{substance2}` - Interaction checker\n- `/v1/timezone/...` - Timezone utility endpoints\n- `/v1/datasets/substances` - **Full raw substance dataset download**\n- `/v1/datasets/interactions` - **Full interactions dataset download**\n- `/v1/alcohol/...` - Alcohol database endpoints\n- `/v1/metrics/substances` - **Aggregated substance usage metrics (global)**\n- `/v1/analytics/` - Analytics endpoints\n- `/oauth/...` - OAuth flow endpoints\n- `/v1/auth/irc/...` - IRC authentication endpoints\n- `/.well-known/acme-challenge/` - ACME challenge\n\n### 2. VERSION INFORMATION EXPOSURE\n\n**Critical Finding: Version numbers explicitly exposed in API responses**\n\nPublic endpoints return hardcoded version strings:\n\nFile: `/home/josie/development/personal/josiedot/health/services/core/src/router.cr`\n\nLines 266 & 287:\n```json\n{\n  \"data\": {\n    \"name\": \"Josie Health API\",\n    \"version\": \"1.0.0\"  // <-- Information leakage\n  }\n}\n```\n\nThis is returned at:\n- `/v1/` (API root)\n- `/v1/info` (API info endpoint)\n\n### 3. ERROR MESSAGE INFORMATION LEAKAGE\n\n**Critical Finding: Error responses leak exception details and implementation specifics**\n\nGlobal error handler (lines 180-184 in router.cr):\n```crystal\nrescue ex\n  context.response.status_code = 500\n  context.response.content_type = \"application/json\"\n  context.response.print({\"error\" => \"Internal server error: #{ex.message}\"}.to_json)\n```\n\nThis leaks the raw exception message from any unhandled error. Examples of what could leak:\n- File paths (via File.read errors at lines 303, 316, 329)\n- Library version information\n- Stack traces details\n- Internal service names\n\nSpecific error message leakage examples found in handlers:\n\nFile: `substance_handler.cr` (line 253):\n```crystal\nrescue ex\n  response.status_code = 400\n  response.print({\"error\" => \"Invalid request: #{ex.message}\"}.to_json)\n```\n\nFile: `router.cr` (lines 310, 323, 337):\n```crystal\n{\"error\" => \"OpenAPI spec not found: #{ex.message}\"}\n{\"error\" => \"Swagger UI not found: #{ex.message}\"}\n{\"error\" => \"Logo not found: #{ex.message}\"}\n```\n\n### 4. SWAGGER UI & OPENAPI DOCUMENTATION EXPOSURE\n\nThe full API documentation is publicly accessible at `/` and `/v1/openapi.yaml`:\n\n- **Swagger UI** at `/` (static/swagger-ui.html) - displays full API documentation\n- **OpenAPI 3.0.3 spec** at `/v1/openapi.yaml` and `/openapi.yaml` - machine-readable API definition\n\nThe OpenAPI spec exposes:\n- All endpoint paths and HTTP methods\n- Request/response schemas\n- Authentication mechanisms (BasicAuth, Bearer token with prefix `jhapi_`)\n- Callback URL parameters used for internal webhooks\n- Environment-specific server URLs (production and development)\n\nLines 10-14 in openapi.yaml:\n```yaml\nservers:\n- url: https://api.josie.health\n  description: Production\n- url: http://localhost:3001\n  description: Local development\n```\n\n### 5. FULL DATABASE DOWNLOADS\n\n**Critical Finding: Complete public database exports available**\n\nUnauthenticated users can download complete datasets:\n\n- `GET /v1/datasets/substances` - Returns entire substance database with all properties\n- `GET /v1/datasets/interactions` - Returns complete interaction matrix\n\nThis is implemented in substance_handler.cr (lines 430-437):\n```crystal\nprivate def handle_substances_data(response : HTTP::Server::Response)\n  response.print(substances_data.to_json)\nend\n\nprivate def handle_interactions_data(response : HTTP::Server::Response)\n  response.print(JosieHealth::LUT::DataFiles.combos.to_json)\nend\n```\n\n### 6. AGGREGATED USAGE METRICS EXPOSURE\n\n**Medium Risk: Anonymous aggregated metrics available to unauthenticated users**\n\n`GET /v1/metrics/substances` returns top substances by usage count globally:\n\n```json\n{\n  \"data\": [\n    {\"substance\": \"caffeine\", \"tally\": 45},\n    {\"substance\": \"modafinil\", \"tally\": 23}\n  ],\n  \"meta\": {\n    \"total_entries\": 68,\n    \"source\": \"redis\"\n  }\n}\n```\n\nThis allows attackers to:\n- Identify most commonly used substances in the system\n- Track usage patterns over time by querying with year parameter\n- Infer user base size from total_entries\n\n### 7. RESPONSE HEADERS - GOOD SECURITY PRACTICE\n\n**Positive Finding: Security headers are properly set (lines 64-67 in router.cr):**\n\n```\nX-Frame-Options: DENY\nX-Content-Type-Options: nosniff\nStrict-Transport-Security: max-age=31536000; includeSubDomains\nContent-Security-Policy: default-src 'none'; frame-ancestors 'none'\n```\n\n**However:** No explicit `Server` header suppression found. Crystal's HTTP library may expose a default Server banner.\n\n### 8. CORS POLICY EXPOSURE\n\nCORS headers are set but relatively permissive for public endpoints (lines 73-77):\n\n```\nAccess-Control-Allow-Origin: (from request origin)\nAccess-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE, OPTIONS\nAccess-Control-Allow-Headers: Content-Type, Authorization\n```\n\nThis is set to `*` for static assets (logo, Swagger UI) making them accessible from any origin.\n\n### 9. RATE LIMITING INFORMATION\n\n`X-RateLimit-*` headers leak rate limiting configuration:\n\nLines 92-93 in router.cr:\n```\nX-RateLimit-Remaining: (current remaining)\nX-RateLimit-Limit: (from RATE_LIMIT_BUCKET_SIZE environment variable)\n```\n\nThis allows attackers to:\n- Determine exact rate limit threshold (default 60 requests)\n- Calculate refill rate from X-RateLimit-Remaining changes\n- Optimize brute force attacks\n\n### 10. REDIS CONNECTION DETAILS (MINOR)\n\n`GET /health` endpoint response (lines 255-259):\n\n```json\n{\n  \"status\": \"ok\",\n  \"service\": \"logs-api-redis\",\n  \"redis_connection\": \"connected\"\n}\n```\n\nLeaks the Redis-backed architecture. Error case could leak more:\n```crystal\n\"redis_connection\" => \"error: #{ex.message}\"\n```\n\n### 11. USER ID ENUMERATION VECTOR\n\nWhile user-specific endpoints are authenticated, the OpenAPI spec explicitly documents user ID path parameters:\n\n```yaml\n/v1/metrics/users/{user_id}/lastdose:\n/v1/metrics/users/{user_id}/tally:\n/v1/users/{user_id}/timezone:\n```\n\nThis reveals the system uses simple user IDs (likely Discord IDs or usernames) that may be enumerable.\n\n### SUMMARY OF CRITICAL FINDINGS\n\n| Finding | Severity | Type | Impact |\n|---------|----------|------|--------|\n| Exception messages in error responses | HIGH | Information Disclosure | Leaks implementation details |\n| Complete database downloads (/datasets) | HIGH | Information Disclosure | Attacker gains full substance/interaction data |\n| OpenAPI spec exposes all endpoints | HIGH | API Mapping | Complete API surface documented |\n| Version numbers in responses | MEDIUM | Information Disclosure | Enables version-specific attack research |\n| Aggregated usage metrics | MEDIUM | Information Disclosure | Reveals user base patterns |\n| Rate limit configuration in headers | MEDIUM | Information Disclosure | Enables attack optimization |\n| Redis backend exposed in health check | LOW | Information Disclosure | Reveals infrastructure details |\n\n### RECOMMENDATIONS\n\n1. **Remove exception messages from error responses** - Return generic \"Internal Server Error\" for 5xx errors\n2. **Restrict /datasets/ endpoints** - Require authentication or remove entirely\n3. **Hide OpenAPI spec** - Don't serve /openapi.yaml to unauthenticated users, or require basic auth\n4. **Remove version numbers** - Don't advertise version in API responses\n5. **Suppress rate limit headers** - Or make them generic (don't expose exact bucket size)\n6. **Add Server header filtering** - Explicitly set to generic value or omit\n7. **Audit error handling across all handlers** - Ensure no exception details leak\n8. **Consider hiding /metrics/substances** - Or require authentication if it's meant to be private"}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":5,"cache_creation_input_tokens":6386,"cache_read_input_tokens":108955,"output_tokens":2317,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":6386,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYYS68aQneW5AMJ1LiYpy","type":"assistant","uuid":"cbe06bdd-afa6-4323-9ca6-ad22bfeffa6d","timestamp":"2026-02-27T10:41:59.414Z"}
