Security checks for vulnerabilities and agentic risk

Overview

The skill coherently documents a hosted data service and webhook receiver, with disclosed credential use, storage, and security limitations.

Protect the API key and webhook URLs, and consider service charges and provider retention before sending sensitive queries or events. Treat webhook deliveries as unverified notifications; independently confirm events before financial or account actions. The hosted backend and optional MCP implementation were not audited.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

| Method | Path | Summary |

| `POST` | `/v1/webhook-endpoints` | Create a new superagnt webhook endpoint. Returns { id, name, url } where `url` is a public HTTPS endpoint of the form https://api.superagnt.com/webhooks/ingest/<id>. Give that URL to a third party (Stripe, Calendly, GitHub, your own service, etc.) so they can POST events to it. superagnt stores every inbound POST as a "delivery" the agent can later fetch with superagnt_webhooks_list_deliveries. The `name` is a workspace-unique label (3-50 chars, lowercase + hyphens) that you can show to the user; it is NOT part of the receive URL. Use this when the user asks to "set up a webhook", "give me a URL to receive events", or "let me ingest events from <vendor>". |
| `GET` | `/v1/webhook-endpoints` | List every active webhook endpoint in the workspace. Returns an array of { id, name, description, isActive, createdAt, updatedAt }. Use the `id` from any item as `endpointId` for superagnt_webhooks_get_en

| Get full details of a single webhook endpoint by id. Returns { id, name, description, isActive, createdAt, updatedAt }. Use this when you have an endpoint id (e.g. from superagnt_webhooks_list_endpoints) and need its full record. Note: this does NOT return the receive URL — reconstruct it as https://api.superagnt.com/webhooks/ingest/{id} if you need to show it again. |
| `DELETE` | `/v1/webhook-endpoints/{id}` | Soft-delete (deactivate) a webhook endpoint by id. After deletion the receive URL https://api.superagnt.com/webhooks/ingest/{id} stops accepting POSTs (returns 404). Existing delivery history is retained and still queryable. Use this when the user wants to stop receiving events on an endpoint or rotate to a new one. ALWAYS confirm with the user before deleting — third parties posting to the URL will start failing immediately. |
