Security audit

Zotero

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Zotero through OOMOL, but its setup instructions include unverified remote shell installation commands that should be reviewed before use.

Review the OOMOL oo CLI installation path before installing. Prefer a versioned installer with integrity verification, and approve any Zotero write or delete action only after checking the exact target and payload.

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

External Script Fetching

Finding

The skill instructs the agent to install software via a remote script piped directly into a shell (curl ... | bash). This pattern is dangerous because it executes network-fetched code without verification, so a compromised host, CDN, DNS path, or upstream script could lead to arbitrary code execution on the user's machine.

Finding

The description says to use this skill for "ANY Zotero request" and "Whenever a task involves Zotero," which is very broad and overlaps with many ordinary mentions of Zotero-related work. It does not provide narrower trigger boundaries or exclusion examples, increasing the chance of unintended invocation.
