LiveAgent

Security checks for vulnerabilities and agentic risk

Overview

The LiveAgent workflow has clear safeguards, but its automatic setup can execute unverified software and introduce broader agent changes.

Review and approve the CLI installation separately before allowing automatic setup. Check its bundled-skill synchronization behavior and disable it if unwanted. Connect only the LiveAgent permissions you need, understanding that OOMOL handles the integration's credentials and data. The downloaded installers and hosted connector implementation were not verified.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command executes an Oomol installation script rather than implementing a LiveAgent operation. No connection between this installer and the declared LiveAgent functionality is established, so it cannot be treated as a demonstrated supporting implementation detail. The downloaded script's contents and further effects are not visible in this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

Piping the HTTPS installer directly into bash gives the remote response immediate code execution with the invoking process's privileges. HTTPS protects transport but does not protect against a compromised distribution endpoint or malicious publisher update; this is the same underlying installation weakness identified by SQP-2, not a separate exploit chain.

Fallback setup executes downloaded scripts without warning about remote-code execution risks.

Medium
Category
Output Handling
Confidence
97% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell code without inspecting it, verifying an independently trusted integrity value, or obtaining explicit installation approval. A compromised installer endpoint or malicious installer update could execute arbitrary code with the agent's local privileges; limiting this to missing-CLI failures reduces exposure but does not remove the 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.
