Veremark

Security checks for vulnerabilities and agentic risk

Overview

This Veremark connector skill is mostly coherent, but it includes first-time setup instructions that may run a remote installer script directly in the shell.

Before installing, review the oo CLI installation path and prefer a verifiable package or official installer. Use this skill only with a Veremark account you intend the agent to access, and confirm candidate/request details before any create_request action.

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

Finding

The skill instructs users to install software via a remote script piped directly into a shell, which is a well-known supply-chain and arbitrary code execution risk. If the install endpoint, transport, or upstream distribution is compromised, running the command would execute attacker-controlled code on the user's system with the user's privileges.

Finding

The description says to use this skill for "ANY Veremark request" and "Whenever a task involves Veremark," which is an unusually broad trigger for a manifest/markdown file. This can overlap with many ordinary references to Veremark and does not define boundaries or exclusion cases for when the skill should not activate.
