Security audit

Namely

Security checks for vulnerabilities and agentic risk

Overview

The Namely integration fits its stated purpose, but missing-CLI setup directs the agent to execute unverified downloaded code without a clear approval step.

Review and approve CLI installation separately before allowing automatic setup, including its bundled-skill installation behavior. Connect only an authorized Namely account with the minimum employee-data access needed, and consider OOMOL's role in handling authentication and requests. The downloaded installer and hosted connector 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs remote code execution from an Oomol installation endpoint rather than searching or reading Namely data. Nothing in the supplied chunk establishes that this installation is a supporting dependency for Namely access. The downloaded script's contents and further effects are not available for assessment.

Content

No source excerpt is available for this finding.

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

## Available actions

- `get_current_profile` — Get the Namely profile associated with the personal access token.
- `get_profile` — Get one Namely employee profile by profile ID.
- `list_profile_fields` — List Namely profile fields configured for the company.
- `list_profiles` — List Namely employee profiles visible to the personal access token.

## Safety

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable HTTPS response directly into bash executes remote code without a pinned version or independent integrity verification. Compromise of the installer distribution path could execute attacker-controlled code with the user's privileges; the conditional setup trigger reduces exposure but does not remove this supply-chain risk, and the PowerShell alternative has the same weakness.

Fallback setup executes remotely downloaded installation scripts without warning the user about the system impact.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell installation code without requiring informed approval for local system changes. Although conditional and relevant to setup, this expands a read-oriented Namely task into arbitrary code execution with the invoking user's privileges; actual execution also depends on the agent's tool 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.

- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.
