Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent eToro API reference, but it enables live trading and other account-changing actions without clear confirmation safeguards.

Install only if you intend to let an agent access your eToro account. Prefer Virtual/Demo or read-only keys, and do not provide write-enabled real portfolio credentials unless you have separate controls requiring explicit approval for every live trade, close, cancel, watchlist change, or feed post.

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

Tool Parameter Abuse

High

Category: Tool Misuse
Content: Endpoints: - `DELETE /trading/execution/demo/market-open-orders/{orderId}` - `DELETE /trading/execution/market-open-orders/{orderId}` ### Market Close Orders
Confidence: 80% confidence
Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Tool Parameter Abuse

High

Category: Tool Misuse
Content: - `POST /trading/execution/demo/limit-orders` - `DELETE /trading/execution/demo/limit-orders/{orderId}` - `POST /trading/execution/limit-orders` - `DELETE /trading/execution/limit-orders/{orderId}` Body (PascalCase, JSON):
Confidence: 80% confidence
Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Tool Parameter Abuse

High

Category: Tool Misuse
Content: Query: `name` (required), `type`, `dynamicQuery` (optional). (Uses query params, not a JSON body.) - `PUT /watchlists/{watchlistId}` Query: `newName` (required). (Uses query params, not a JSON body.) - `DELETE /watchlists/{watchlistId}` **Watchlist items (body schema)**
Confidence: 80% confidence
Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Tool Parameter Abuse

High

Category: Tool Misuse
Content: - `POST /watchlists/{watchlistId}/items` - `PUT /watchlists/{watchlistId}/items` - `DELETE /watchlists/{watchlistId}/items` Example body:
Confidence: 80% confidence
Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings

Medium

Confidence: 93% confidence
Finding: The skill explicitly enables real trade execution and cancellation but does not provide a prominent warning that non-demo endpoints can place or close real positions with irreversible financial consequences. In an agent setting, this increases the chance that an LLM or automation layer will invoke live trading actions without sufficient user confirmation or risk acknowledgment.

External Transmission

Medium

Category: Data Exfiltration
Content: Example: ```bash curl -X GET "https://public-api.etoro.com/api/v1/watchlists" \ -H "x-request-id: <UUID>" \ -H "x-api-key: <PUBLIC_KEY>" \ -H "x-user-key: <USER_KEY>"
Confidence: 60% confidence
Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
