Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly scoped Reddit data integration that sends requested Reddit lookups to Superagnt’s API using the user’s API key.

Install only if you are comfortable sending Reddit search terms, usernames, subreddit names, post URLs, and your Superagnt API key to Superagnt’s service. Avoid using it for sensitive or regulated research targets unless that external processing is approved, and review the OAuth consent screen if you choose the optional MCP setup.

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

Missing User Warnings

Finding

The skill clearly sends user-supplied Reddit queries, usernames, subreddit names, and URLs to a third-party service, but the surrounding description does not prominently warn users that their inputs and metadata leave the local environment. This can mislead users and downstream agents into disclosing research targets or sensitive identifiers to an external processor without informed consent.
