Security audit

SamCart

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent SamCart reader, but its setup asks users to execute a remote installer script and its wording leaves some authority boundaries ambiguous.

Review the installer source and prefer a verified installation method before using this skill. Install only if you are comfortable connecting OOMOL to SamCart business/customer data, and treat the skill as read-only unless the live connector schema clearly exposes additional actions and you explicitly approve them.

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
Not specified by scanner
Confidence
98% confidence
Finding

The manifest says the skill is for 'searching and reading data,' but the body also describes support for state-changing '[write]' and '[destructive]' actions. This mismatch can mislead an orchestrator or reviewer into granting the skill broader authority than expected, increasing the risk of unintended modification if write actions are later exposed through the connector.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The skill instructs users to install software via 'curl ... | bash', which executes a remotely fetched script without prior verification. If the remote host, transport, or distribution pipeline is compromised, this can lead to arbitrary code execution on the user's machine.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The phrase 'Use this skill for ANY SamCart request' is overly broad and may cause the skill to be invoked for loosely related tasks without sufficient scoping. Broad routing language can bypass least-privilege decision-making and funnel operations into a connector-backed path even when the task does not require it.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The documentation asserts that actions tagged '[write]' or '[destructive]' exist and gives execution guidance for them, but the enumerated action list contains only read operations. This inconsistency creates ambiguity about the real capability surface, which can cause unsafe assumptions during review or future expansion without proper guardrails.
