Axiom

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Axiom through OOMOL, but its first-time setup tells users or agents to execute a remote installer directly in a shell without verification.

Review this skill before installing. Its Axiom actions are disclosed and include confirmation guidance for writes and deletes, but do not let an agent run the remote installer automatically; install the oo CLI through a trusted, verified method and confirm any dataset creation or deletion 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: 97% 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 supply-chain and remote code execution risk: if the hosting endpoint, CDN, DNS, TLS trust chain, or published install script is compromised, arbitrary code will execute immediately on the user's machine without review.
