Security audit

SocialKit Reddit Draft

Security checks for vulnerabilities and agentic risk

Overview

The skill prepares Reddit drafts and leaves posting under your control, with no hidden network activity in the bundled helper.

Review the separate socialkit-social-core dependency before using initialization. Check the subreddit, text, and flair before posting. The submission link contains draft content and sends it to Reddit when opened. The bundled helper was fully inspected despite partial scanner coverage; the separate dependency remains outside this assessment.

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
