Security audit

BotStar

Security checks for vulnerabilities and agentic risk

Overview

The BotStar controls are clear, but setup needs review because it executes downloaded code without verification or a separate approval step.

Review and approve CLI installation separately, preferably using a verified fixed release. Check its automatic skill synchronization settings before running it. OOMOL mediates your BotStar access; connect an appropriately limited account and retain the required confirmations for writes, publishing, and deletion. The installer scripts were not available for content verification, so their complete effects remain uncertain.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied chunk contains only an Oomol installer command and no BotStar interaction. Although dependency installation can be a supporting implementation detail, the provided content establishes no connection between this installer and BotStar functionality. The downloaded script's contents and any additional effects are not visible.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

Piping a remotely fetched script directly into Bash executes mutable network-delivered code with the agent process's local privileges, without integrity verification or review. HTTPS and the apparently relevant vendor domain reduce some exposure but do not prevent a compromised distribution endpoint from serving code that steals accessible data or modifies the system; the PowerShell alternative has the same underlying risk.

Fallback installation executes downloaded scripts without warning about local system changes.

Medium
Category
Output Handling
Confidence
91% confidence
Finding

The fallback directs the agent to install local software after a missing-command error without explicitly obtaining approval for system changes. Although setup is relevant and conditional, a request to operate BotStar does not necessarily authorize downloading and executing a local installer; the actual execution also depends on the host's tool permissions.

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.
