Ayrshare

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Ayrshare, but its setup instructions tell the agent to run a remote installer script directly on the user’s machine.

Install only if you trust OOMOL and the oo CLI installer source. Prefer reviewing the installer or using official documented package-manager steps before running it, and require explicit confirmation before publishing, updating, or deleting Ayrshare posts.

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

External Script Fetching

Finding

The skill instructs the agent to install software by piping a remote script directly into bash, which is a classic supply-chain and remote code execution risk. If the install endpoint, transport path, or hosting environment is compromised, arbitrary code could run immediately on the user's machine without review.

Finding

The description says to use this skill for "ANY Ayrshare request" and "Whenever a task involves Ayrshare," which is a very broad activation condition. It does not provide narrower trigger constraints or exclusion examples, so ordinary mentions of Ayrshare-related tasks could invoke the skill too aggressively.
