Security audit

ClickMeeting

Security checks for vulnerabilities and agentic risk

Overview

The ClickMeeting workflow is coherent, but its automatic setup can execute unverified remote code without separate user approval.

Review and approve the CLI installation separately before allowing setup, preferably using a pinned release with independently verified integrity. Connecting ClickMeeting lets OOMOL mediate access to meeting data and room tokens. The bundled instructions require confirmation for account changes, but the unavailable remote installer remains outside this inspection.

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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied chunk only runs an external installer; it contains no ClickMeeting operations or evidence connecting the installation to ClickMeeting functionality. On the supplied evidence, this is a materially different behavior rather than an established supporting implementation detail. The downloaded script's contents and further effects are not available for assessment.

Content

No source excerpt is available for this finding.

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a downloaded script directly into Bash executes mutable remote content without a pinned version or independent integrity verification; the PowerShell alternative has the same weakness. If the distribution endpoint or release pipeline is compromised, the installer can execute attacker-controlled code with the invoking user's permissions, potentially accessing local files and credentials.

Content

The setup workflow executes downloaded installation scripts without warning about local system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
91% confidence
Finding

The setup instructions direct installation after a missing-command error without explicitly requiring approval for executing remote code and changing the local system. Confirmation requirements cover ClickMeeting mutations but not installation, creating an authorization gap; the conditional setup trigger limits exposure but does not establish user 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.

- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.
