Security audit

TMDB

Security checks for vulnerabilities and agentic risk

Overview

The TMDB features fit the stated purpose, but setup can execute unverified downloaded code without a clear user approval step.

Review and approve CLI installation separately, using a verified version. Consider disabling its managed-skill synchronization if you only want TMDB functionality; the [CLI reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md) documents OO_SKILLS_SYNC_DISABLED. Your TMDB requests and account connection use OOMOL. No malicious payload was established, but the downloaded installer could not be inspected.

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

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution and contains no TMDB search or read operation. Nothing in the supplied chunk establishes that this installer supports TMDB functionality, so its behavior is materially different from the declared purpose. The downloaded script's contents and further effects are not visible.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs a login operation rather than the declared TMDB search and reading functions. Authentication can be a supporting implementation detail, but the snippet provides no connection between oo and TMDB and contains no TMDB functionality.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes an unpinned HTTPS response directly into bash without verifying the downloaded artifact. A compromised installation endpoint or delivery infrastructure could therefore run attacker-controlled code with the agent's permissions; HTTPS alone does not establish installer integrity, and this is the same underlying installation risk noted in SQP-2.

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

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The setup fallback instructs the agent to execute remotely downloaded shell or PowerShell scripts without an explicit approval checkpoint or artifact verification. If the installer source is compromised, it could execute arbitrary code with the agent's local permissions; triggering installation only when the CLI is missing reduces exposure but does not remove this risk.

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.
