SupportBee

Security checks for vulnerabilities and agentic risk

Overview

The SupportBee workflow is clearly scoped, but its fallback setup executes changing remote code without clearly limiting or approving local changes.

Review setup before installing. Prefer a separately approved, verified CLI release, and review its automatic skill synchronization. OOMOL mediates access to your SupportBee account and data. Keep confirmation requirements for changes and customer replies. The downloaded installers could not be inspected, so their exact local 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The supplied chunk performs remote script execution rather than any observable SupportBee operation. Dependency installation could be a supporting implementation detail, but the provided content establishes no connection between this installer and the declared SupportBee functionality. The downloaded script's contents and further effects are not available for assessment.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable remote script directly into bash without version pinning or independent integrity verification. Compromise of the installation endpoint or its publishing infrastructure could execute attacker-controlled code with the agent's privileges; HTTPS protects transport but does not establish that the delivered code is trustworthy.

Content

The setup workflow executes downloaded installation scripts without warning about running remote code or modifying the local system.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback workflow directs the agent to execute downloaded shell or PowerShell code without explicit installation approval or disclosure of local-system changes. Although limited to a missing-CLI error, this converts a SupportBee task into local code execution with the agent's privileges; the state-change confirmations elsewhere only address SupportBee data.

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.
