Security audit

AIsa Youtube Serp Scout

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed YouTube search client that sends user search terms to AIsa's API using an AISA_API_KEY, with no hidden persistence or local account access found.

Before installing, confirm you trust AIsa with YouTube search queries, filter tokens, and authenticated API usage tied to AISA_API_KEY. Avoid using it for sensitive private research terms if those should not be sent to api.aisa.one.

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
Findings (5)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
90% confidence
Finding

The skill declares that it requires environment access and makes network requests, but it does not explicitly constrain tool scope with permissions or allowed-tools. In an agent ecosystem, that omission can allow broader-than-necessary execution or make sensitive capabilities less visible to reviewers, increasing the chance of unintended secret exposure or outbound requests.

External Transmission

Data Exfiltration
Confidence
60% confidence
Finding

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

This code file performs outbound network requests to a remote API using both the user's search terms and a bearer token from the environment, but the runtime path provides no confirmation prompt or user-visible notice that data will be sent off-system. While network access is central to the client’s purpose, the code lacks any explicit disclosure in the CLI output or comments for this transmission behavior and credential use.
