Security audit

Agora

Security checks for vulnerabilities and agentic risk

Overview

Agora changes require approval, but setup runs an unverified remote installer and may introduce broader agent changes than the skill explains.

Review and verify the CLI installation yourself before use, including its automatic installation of other agent skills. Consider disabling that synchronization and limiting the connected Agora account's permissions. Keep the required approvals for project and certificate changes. Remote installer and connector implementations were not verified.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs remote installer execution, not Agora data operations. Nothing in the code establishes that installing the Oomol CLI is a supporting implementation detail for Agora access. The downloaded script's contents are not supplied, so its subsequent behavior cannot be determined.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup command downloads a mutable remote script and immediately executes it without inspecting it or verifying a pinned version and trusted signature or digest. Compromise of the distribution endpoint or installer could execute arbitrary code with the invoking user's privileges, potentially exposing local credentials or modifying files. Its legitimate dependency-installation purpose and missing-CLI trigger limit exposure but do not remove the supply-chain risk; the PowerShell example has the same weakness.

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.

- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.

- **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.
