Web of Science Expanded

Security checks for vulnerabilities and agentic risk

Overview

The research functions fit the description, but setup directs the agent to execute unverified downloaded code without clear user approval.

Review and approve CLI setup separately before allowing installation. Prefer an inspected, version-pinned release and review its automatic skill synchronization. Research queries use your OOMOL-connected account and may consume credits. The installer payloads were unavailable for inspection; no malicious behavior was established.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution rather than searching or reading Web of Science data. Nothing in the supplied chunk establishes that this installer is a supporting dependency for the declared purpose. The downloaded script's contents and further effects are not available for assessment.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched script directly into bash executes mutable network-delivered code with the agent process's local permissions, without a pinned version or independent integrity verification; the PowerShell example has the same weakness. Compromise of the distribution endpoint or release process could enable local data theft or modification, despite HTTPS and the legitimate dependency-setup context.

Content

Scanner excerpt · SKILL.md (reported line 60)May include surrounding context.

The setup workflow instructs the agent to execute downloaded installation scripts without warning the user about local system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

When the CLI is absent, the instructions direct the agent to install software without first obtaining approval for local changes and remote-code execution. A request to search bibliographic records does not itself authorize software installation; the missing-command condition limits exposure but does not establish consent.

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.
