Mediastack

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent read-only Mediastack connector, but its setup instructions include unverified remote installer commands that could execute changing external code.

Install only if you are comfortable using OOMOL's oo CLI and Mediastack through an OOMOL-connected account. Do not let an agent run the installer snippets automatically; prefer manually installing from verified OOMOL documentation, checking the installer source or signature/checksum if available, and approving any account login or Mediastack connection step yourself.

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: 98% confidence
Finding: The skill instructs users to install software by piping a remote script directly into a shell (curl ... | bash), which creates a supply-chain and remote code execution risk if the server, transport, DNS, or distribution endpoint is compromised. Because this appears in a skill that an agent may follow during first-time setup, it normalizes executing unverified code and increases the chance of unsafe automated behavior.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The description says to use this skill for "ANY Mediastack request" and "Whenever a task involves Mediastack," which is a very broad activation condition without clear boundaries or exclusion examples. In a manifest file, this can overlap with many ordinary tasks that merely mention Mediastack, making invocation scope ambiguous.
