Retable

Security checks for vulnerabilities and agentic risk

Overview

The Retable workflow controls data changes, but setup can run downloaded code and introduce additional agent skills without clear approval.

Review the CLI installation before allowing automatic setup. Prefer a reviewed version and decide whether it may install additional agent skills; current [CLI documentation](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md) provides OO_SKILLS_SYNC_DISABLED=1 to disable startup skill synchronization. Use narrowly scoped Retable access and retain the required approvals for writes and deletions. The remote installer payload was unavailable for inspection, so its full 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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied chunk performs no visible Retable operations and instead executes an installer from a different service. Nothing supplied establishes this installer as a supporting dependency for Retable. The downloaded script's contents are unavailable, so its further behavior cannot be determined.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The command streams a mutable remote script directly into Bash without an independently verified digest, signature, or pinned version. Compromise of the distribution endpoint or release pipeline could therefore execute attacker-controlled code with the invoking user's permissions; HTTPS and the legitimate CLI dependency do not eliminate this supply-chain risk.

The setup workflow executes downloaded installation scripts without warning the user about remote-code execution or system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The missing-CLI fallback directs execution of downloaded shell or PowerShell scripts without requiring informed approval for local software installation. Although conditional and relevant to the workflow, this expands a Retable data task into local code execution and system changes that the user may not have authorized.

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.
