Security audit

apaleo

Security checks for vulnerabilities and agentic risk

Overview

The apaleo actions require appropriate user approval, but first-time setup directs execution of unverified downloaded code without a separate approval step.

Review setup before enabling this skill. Install a verified CLI release yourself, review its management of other agent skills, and prevent automatic remote-installer execution. OOMOL mediates account access and receives requested operation payloads. Continue requiring approval for exact write and deletion targets; the external installers and hosted connector 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

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

The supplied command performs remote software installation rather than any visible apaleo operation. Although installing a CLI could be a supporting implementation detail, the supplied content establishes no relationship between this installer and the declared apaleo functionality. The downloaded script's contents and subsequent effects are not available for assessment.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable remote script directly into bash executes its contents with the agent process's local permissions, without version pinning or integrity verification. Compromise of the installer distribution could therefore expose accessible files and credentials or modify the environment; HTTPS and the legitimate CLI dependency do not eliminate this supply-chain risk.

Fallback setup executes remote installation scripts without warning about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell code without first obtaining explicit approval for local installation and its system changes. The missing-CLI condition limits exposure, but an apaleo request does not itself authorize arbitrary installer execution on the user's machine.

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.
