Security audit

Apiframe

Security checks for vulnerabilities and agentic risk

Overview

The Apiframe integration is coherent, but its setup instructions execute an unverified remote installer without a separate approval step.

Review and install a verified CLI release separately before enabling this skill. Check its automatic skill synchronization settings and permit only the connected accounts you intend to use. Requests pass through OOMOL, and generation can consume credits. The bundled instructions were fully reviewed, but the remote installer and live service implementation 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command runs an Oomol installer, with no demonstrated connection to Apiframe. Nothing in the chunk establishes this installation as a supporting dependency for the declared functionality. The downloaded script's contents are not supplied, so its additional effects cannot be determined.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an unpinned HTTPS response directly into bash executes whatever the installation endpoint supplies, without independently verifying its integrity or reviewing it first. Compromise of the distribution endpoint or release process could therefore execute attacker-controlled code with the agent's local permissions; the PowerShell alternative has the same underlying risk.

The setup fallback executes downloaded installation scripts without a system-integrity warning.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback instructs the agent to execute downloaded installation code without explaining the host-level effects or requesting installation-specific approval. Although this is legitimate dependency setup, it crosses from Apiframe operations into local software execution; the declared Bash(oo *) restriction may limit execution if enforced, but does not make the setup instructions safe.

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.
