Security audit

Agility CMS

Security checks for vulnerabilities and agentic risk

Overview

The CMS workflow fits its purpose, but setup can execute unverified installers and introduce broader agent changes without clear user control.

Review setup before enabling this skill. Install a verified CLI release yourself, approve any agent-skill changes, and consider disabling managed-skill synchronization using the documented OO_SKILLS_SYNC_DISABLED setting. OOMOL mediates CMS access, so connect only the intended account with read-only permissions where available. The remote installers and hosted implementation were not verified; the supplied artifacts do not establish malicious behavior.

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

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command runs an Oomol installer, with no visible Agility CMS interaction. Installing and executing remote software is not declared, and the supplied code establishes no connection showing that this is a supporting implementation detail for Agility CMS access. The remote script's exact effects cannot be determined from this chunk.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

The only supplied behavior is a login command, rather than the declared Agility CMS data-access functionality. Authentication could be a supporting implementation detail, but this chunk provides no evidence that the command authenticates to Agility CMS or supports the described operations.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable remote script directly into Bash without pinning or verifying the downloaded code. HTTPS protects transport but does not protect against a compromised distribution endpoint or malicious release, which could result in arbitrary execution under the user's account; the legitimate setup context reduces suspicion of malicious intent, not the technical risk.

The setup workflow executes remotely downloaded installer scripts without warning the user about the trust and system-modification implications.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The fallback setup directs the agent to execute downloaded shell or PowerShell code without explicit approval or disclosure of the resulting system changes. Although conditional and relevant to setup, this crosses from reading CMS data into arbitrary local code execution; a compromised installer could access files and credentials or establish persistence with the invoking user's permissions.

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.
