Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Exa search helper, but users should remember that search terms and advanced research requests go to Exa's external MCP service.

Install only if you are comfortable sending search queries, URLs, company names, and people-search terms to Exa. Do not include secrets, credentials, confidential business details, or sensitive personal information in queries, and enable the advanced tool bundle only when you actually need those tools.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill advertises external search functionality but does not warn users that their queries and research terms are transmitted to Exa's remote MCP service. Users may inadvertently send sensitive prompts, internal project names, or proprietary research topics off-platform without informed consent, creating privacy and data-handling risk.

Missing User Warnings

Confidence
94% confidence
Finding

The documentation exposes crawling and people-search capabilities without any warning that these features may collect, retrieve, or transmit privacy-sensitive information to an external third party. In context, these tools increase the chance of collecting personal or regulated data and make the omission of privacy guidance more dangerous than a basic web-search skill.

Unrestricted Tool Access

Medium
Category
Excessive Agency
Confidence
84% confidence
Finding

The skill explicitly instructs users to enable all available tools, including crawling, people search, and autonomous research functions, rather than following least-privilege principles. This broadens accessible capabilities unnecessarily and increases exposure to privacy misuse, over-collection, and accidental invocation of higher-risk external actions.
