Security audit

ProcessPlan

Security checks for vulnerabilities and agentic risk

Overview

The ProcessPlan actions have sensible controls, but setup can execute unverified remote software with broader effects than the skill explains.

Review and approve CLI setup separately before letting the agent install it. Use a vetted release and inspect its installer. Consider disabling automatic skill synchronization using the publisher's documented OO_SKILLS_SYNC_DISABLED setting. OOMOL will mediate your ProcessPlan access and data. No malicious behavior was established, but the remote installer could not be inspected.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code installs or runs external software rather than performing any visible ProcessPlan operation. No connection is shown that would establish this installer as a supporting implementation detail for the declared purpose. The downloaded script's contents are not supplied, so its further behavior cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash pipeline executes the current contents of a remote installer without a pinned version or independent integrity verification. HTTPS protects transport but does not protect against a compromised publishing account or installer host, which could deliver code capable of accessing local files and credentials; this is the same underlying installation risk flagged by SQP-2.

Content

The setup workflow executes downloaded installation scripts without warning about running remote code on the user's system.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The setup instructions direct the agent to execute downloaded shell or PowerShell code without explaining that this grants remote code the local user's privileges or requiring installation approval. Although limited to first-time setup, a missing dependency can trigger a transition from a ProcessPlan task to arbitrary local code execution if the installer delivery 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.
