Security checks for vulnerabilities and agentic risk

Overview

The Simla workflow has clear safeguards, but its setup can execute unverified remote installers without a separate approval step.

Review the CLI installation separately before allowing setup to run. Prefer a verified, pinned release and inspect its agent-skill synchronization settings. OOMOL will mediate access to your Simla records; retain the skill's confirmation requirements for changes. Both remote installer retrieval attempts failed, so their contents remain unreviewed.

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

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
93% confidence
Finding

The supplied code performs remote software installation rather than the declared Simla.com data operations. Although dependency installation can be a supporting implementation detail, this chunk provides no evidence connecting the Oomol installer to the declared purpose. The downloaded script's contents are not supplied, so its further behavior cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable remote script directly into Bash executes its contents with the agent's local privileges without integrity verification or an opportunity for prior inspection. Compromise of the distribution endpoint could enable credential theft or local file modification; HTTPS and the legitimate CLI prerequisite reduce some risks but do not prevent supply-chain compromise. The PowerShell installation command has the same weakness, and this finding overlaps SQP-2.

The setup workflow executes remotely downloaded installation scripts without warning about local system changes or the trust required.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

When the CLI is missing, the skill directs the agent to execute an external installer without explicit user approval or disclosure of local system changes. This crosses from the requested CRM operation into local code execution; the conditional setup reduces exposure but does not establish consent or installer integrity.

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.
