StoreCensus

Security checks for vulnerabilities and agentic risk

Overview

The StoreCensus reading workflow is coherent, but its setup instructions execute remote installers without a clear approval or verification step.

Prefer an existing, reviewed oo installation. Require separate approval before setup, verify the downloaded software, and review any automatic bundled-skill changes. StoreCensus requests use your OOMOL-connected account. The remote installer contents and their exact local effects remain unverified; no malicious behavior was established.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code performs remote script installation rather than searching or reading StoreCensus data. Nothing in the chunk establishes the installer as a supporting dependency for StoreCensus functionality. The installer's downstream actions cannot be determined from the supplied code.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remote script directly into bash executes mutable network-supplied code with the invoking user's privileges, without a review or integrity-verification step; the PowerShell example has the same weakness. Compromise of the distribution endpoint could therefore lead to local data theft or arbitrary system changes, although installation is only a fallback and no compromise is demonstrated here.

Content

The setup workflow executes remote installation scripts without warning about local system changes or the trust implications.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The fallback directs the agent to install software without first explaining local changes or obtaining explicit approval. A request to read StoreCensus data does not necessarily authorize installing software, although the missing-CLI condition limits when this workflow is reached.

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.
