Security audit

Sendspark

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Sendspark through OOMOL, but its first-time setup includes unverified remote installer commands that execute downloaded code directly.

Review the installer path before using this skill. Normal Sendspark actions appear scoped and disclosed, but first-time setup should preferably use a verified, pinned, or package-manager install method instead of piping downloaded scripts directly into a shell.

Vulnerability Patterns
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • 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

High
Category
Supply Chain
Confidence

Finding

The skill instructs the agent to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This creates a direct remote code execution path: if the install endpoint, transport, hosting, or upstream release process is compromised, arbitrary code will run on the user's machine with the current user's privileges.

Finding

The description says to use this skill for "ANY Sendspark request" and "Whenever a task involves Sendspark," which is a very broad activation condition. It does not provide narrower trigger examples, exclusions, or constraints, increasing the chance of accidental invocation for loosely related mentions of Sendspark.
