Security audit

Laravel Cloud

Security checks for vulnerabilities and agentic risk

Overview

The Laravel Cloud functions fit the stated purpose, but automatic setup executes unverified remote code without clearly controlling its local changes.

Review and approve CLI installation separately before allowing this skill's setup fallback. Check whether the chosen CLI release installs or updates other agent skills, and disable that behavior if unwanted. Use only the Laravel Cloud permissions needed and understand that OOMOL mediates account access. The remote installer and resulting release 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
  • 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
99% confidence
Finding

The supplied command performs remote code execution for an apparent Oomol CLI installation, not Laravel Cloud searching or reading. Nothing in the supplied content establishes this installation as a supporting dependency for Laravel Cloud access. The downloaded script is not supplied, so its specific downstream actions cannot be determined.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into Bash executes mutable remote content without a review or integrity-verification step. A compromised installation endpoint or release pipeline could therefore execute arbitrary code with the agent's local privileges; the legitimate dependency-setup context explains the command but does not eliminate this supply-chain risk.

Fallback setup executes remote installation scripts without warning about their system-level effects.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The fallback directs an agent handling a read-only Laravel Cloud request to execute a remote installer without explicit approval or an explanation of local system changes. Although conditional on a missing CLI, both installation variants execute downloaded code with the invoking user's privileges, potentially exposing accessible files and credentials if the installer is compromised.

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.
