Security audit

MeetGeek

Security checks for vulnerabilities and agentic risk

Overview

The MeetGeek reader fits its stated purpose, but its fallback setup directs the agent to execute unverified remote installers without clear user control.

Review is warranted for the setup behavior, not the MeetGeek read actions. Install a reviewed, version-pinned CLI yourself and check its changes to other agent skills before connecting an account. OOMOL is a disclosed intermediary for sensitive meeting data. No malicious intent was established, but the remote installers and exact installed CLI behavior could not be audited.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied chunk performs remote installer execution, not MeetGeek data access. Nothing in the supplied code establishes that this installation is a supporting dependency for the declared purpose. The downloaded script's contents and any additional effects are not available for assessment.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command downloads a mutable remote script and immediately executes it without checking a pinned version, independently trusted digest, or signature. Compromise of the installation endpoint or distribution pipeline could therefore execute attacker-controlled code with the agent's local privileges; the legitimate dependency and HTTPS URL do not eliminate this supply-chain risk.

Content

The setup workflow instructs the agent to execute remote installation scripts without warning the user about system changes.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

When the CLI is missing, the skill directs the agent to install software without first obtaining approval for local system changes. Although conditional setup limits exposure, a request to read MeetGeek data does not inherently authorize running an installer with the agent's local permissions.

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.
