Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed remote search helper that sends your search terms to api.rhdxm.com, with no hidden local access, persistence, or destructive behavior found.

Install only if you are comfortable sending search queries to api.rhdxm.com. Do not include secrets, customer data, proprietary project details, credentials, or internal system information in searches.

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
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
87% confidence
Finding

The skill clearly relies on network access to query a remote API, but the manifest does not declare any tool scope such as permissions or allowed-tools. This creates a transparency and policy gap: users and hosting systems may not be able to pre-screen or constrain outbound connectivity even though the skill is designed to transmit user-provided queries externally.

External Transmission

Medium
Category
Data Exfiltration
Confidence
94% confidence
Finding

This skill instructs users to send task queries to a third-party service at api.rhdxm.com. Even though the documentation warns against sending sensitive content, user prompts may still contain proprietary data, credentials, internal system details, or business intent, so the skill enables external data transmission outside the local trust boundary.

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Finding

The MCP connection instruction directs the host to connect over HTTP(S) to a third-party endpoint and use a remote tool. In the context of an agent skill, this increases exposure because prompts or tool arguments may be sent to an external service, potentially disclosing sensitive operational context or enabling dependence on an untrusted remote capability.

Connect via streamable HTTP at `https://api.rhdxm.com/mcp/` with tool: `find_capability`.

Missing User Warnings

Category
Not specified by scanner
Confidence
94% confidence
Finding

The script sends the user's free-form query to a third-party service at api.rhdxm.com without any explicit disclosure, consent prompt, or privacy notice. Because queries may contain sensitive operational details, internal project names, credentials pasted by mistake, or other confidential context, this creates a real data-exposure risk even though the network call is part of the tool's intended functionality.
