Security checks for vulnerabilities and agentic risk

Overview

The research functions fit their purpose, but fallback setup executes unverified remote code without requiring separate user approval.

Review setup before enabling this skill. Install a verified CLI release yourself, check its automatic skill-sync settings, and require approval for additional installation. Searches use your OOMOL-connected account and may consume credit. The remote installers and hosted service implementation were not verified; the concern is uncontrolled setup, not evidence of malicious intent.

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
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs remote software installation, not Web of Science searching or reading. Although dependency installation can be a supporting implementation detail, the supplied chunk establishes no connection between this installer and the declared functionality. The remote script's contents are unavailable, so its further actions cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into Bash executes mutable remote content without checking a pinned version, signature, or trusted digest. If the installation endpoint or its delivery infrastructure is compromised, the script could execute arbitrary commands with the agent process's permissions; the legitimate dependency-installation context does not eliminate this supply-chain risk.

Fallback setup executes downloaded installation scripts without warning the user about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The missing-CLI fallback directs installation through downloaded shell or PowerShell scripts without requiring informed approval for executing external code and changing the local environment. Its conditional placement reduces exposure, and the declared Bash tool restriction may prevent execution in a strictly enforcing host, but a data-search request should not implicitly authorize software installation.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
