Detect Language

Security checks for vulnerabilities and agentic risk

Overview

The skill’s Detect Language actions are coherent, but its setup instructions use unverified remote installer commands that deserve user review before installation.

Install only if you are comfortable trusting OOMOL’s installer endpoint and account setup. Prefer reviewing the installer first or using a verified package/source if available, and avoid running the setup commands automatically in sensitive environments.

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: 94% confidence
Finding: The skill instructs users to install software by piping a remotely fetched script directly into bash, which executes unverified code from the network without inspection or integrity verification. If the install endpoint, transport, or hosting account were compromised, this could lead to arbitrary code execution on the user's machine; because this appears in a setup path for the skill, the context makes the issue more dangerous rather than less.
