Solcast

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Solcast connector helper, but its first-time setup tells users to run unverified remote installer scripts directly in a shell.

Review the first-time setup before installing. Use the skill only if you are comfortable with OOMOL and the oo CLI, and prefer a manually inspected, version-pinned, or signed installer instead of running the provided curl|bash or irm|iex commands directly.

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: 96% 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 code-execution path where a compromised host, CDN, TLS interception, or supply-chain attack could execute arbitrary commands on the user's machine without prior inspection. In this skill context, the risk is heightened because the installation command is presented as an operational fallback inside an agent workflow, increasing the chance it will be run automatically or with reduced scrutiny.
