Security audit

tl;dv

Security checks for vulnerabilities and agentic risk

Overview

The tl;dv operations are appropriately scoped, but setup can execute unverified remote software and introduce broader agent changes without clear user approval.

Review CLI installation separately and verify a fixed release before allowing execution. Check or disable its automatic skill synchronization before use. OOMOL will mediate access to your connected tl;dv account, so consider the sensitivity of meeting content and confirm imports. The installer and resulting binary were not verified; the artifact does not establish malicious intent.

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

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The supplied code performs no visible tl;dv operation and instead executes an installer from a different service. Installation could be a supporting implementation detail if its relationship to tl;dv were established, but no such relationship appears in the supplied chunk. The remote script's contents and any further effects cannot be determined from this code alone.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into bash executes mutable remote content without a pinned version, integrity verification, or review; the PowerShell alternative has the same weakness. Compromise of the installer distribution path could yield arbitrary code execution and access to files or credentials available to the agent, although the file provides no evidence that the current installer is malicious.

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

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback instructs the agent to execute remote shell or PowerShell scripts without first requesting installation approval or explaining the resulting local system changes. Although triggered only when the required CLI is missing, this expands a tl;dv data task into execution of unreviewed code with the agent process's privileges.

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.
