SimpleTexting

Security checks for vulnerabilities and agentic risk

Overview

This SimpleTexting connector skill is coherent and disclosed, with clear write/delete confirmations, but its optional CLI installer guidance should be handled cautiously.

Install only if you intend to let the agent operate your SimpleTexting account through OOMOL. Review and verify the oo CLI installation method before running it, and require explicit approval for any contact, list, or deletion changes.

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

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs the agent to install software by piping a remotely fetched script directly into bash, which executes unverified code from the network without integrity checking or user review. In an adversarial or compromised delivery scenario, this could lead to arbitrary code execution on the host running the skill.

Finding

The invocation text says to use this skill for ANY SimpleTexting request and instead of calling the API directly, which is overly broad and can cause the agent to select this skill whenever SimpleTexting is merely mentioned rather than when the task clearly requires it. That increases the chance of unnecessary tool use and, in this skill, could route users into read, write, or destructive connector operations without tight scope boundaries.
