Security audit

Supervisely

Security checks for vulnerabilities and agentic risk

Overview

The Supervisely reads fit the stated purpose, but setup can execute unverified remote code without a clear user approval step.

Review before installing. Install a verified, pinned CLI separately and require approval before setup changes. Review its automatic skill synchronization and disable it if unwanted, as described in the [CLI controls](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md). Use a limited Supervisely connection and understand that OOMOL mediates credential use and requests. The bundle shows no malicious intent, but does not contain the installer or backend implementation.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs remote installer execution and contains no Supervisely search or read operation. Nothing supplied establishes this installer as a necessary supporting implementation detail for the declared purpose. The downloaded script's contents and any resulting system changes are not visible in this code chunk.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS download directly into Bash executes mutable remote code without verifying its integrity or reviewing it first. Compromise of the distribution endpoint or release pipeline could execute attacker-controlled code with the invoking user's privileges, potentially exposing local credentials and files; the installation context explains the command but does not eliminate this supply-chain risk.

Fallback setup executes downloaded installer scripts without a warning about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback instructs the agent to execute downloaded shell or PowerShell code without first obtaining explicit approval for code execution and system changes. Although conditional dependency installation is legitimate, a missing CLI does not itself authorize executing a remote installer with the user's privileges.

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.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
