ScraperAPI

Security checks for vulnerabilities and agentic risk

Overview

This ScraperAPI integration needs review because setup executes unverified installation scripts and can introduce additional agent skills without clearly requesting approval.

Review and approve a fixed CLI release separately before allowing setup. Check its automatic skill synchronization settings and connect only the intended account. Requests pass through OOMOL and ScraperAPI and may incur charges. The remote installer and server-side implementation were not included in the reviewed artifact.

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 code installs software from an Oomol-hosted endpoint; it does not make a ScraperAPI request. Nothing supplied establishes this installation as a supporting implementation detail for ScraperAPI. The remote script's contents and any additional effects cannot be determined from this chunk.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
91% confidence
Finding

The supplied chunk performs only a CLI login operation and contains no ScraperAPI interaction or evidence that this authentication supports ScraperAPI. Its observable purpose therefore differs materially from the declared purpose.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS download directly into bash executes mutable remote content without first verifying its integrity or reviewing it. A compromised distribution endpoint or malicious installer update could execute arbitrary code and access local data under the agent's privileges; the legitimate setup purpose does not remove this supply-chain risk.

The setup workflow executes remote installation scripts without warning the user about local system changes or obtaining approval.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

A missing CLI triggers instructions to install software without an explicit user-approval checkpoint or disclosure of local changes. Although conditional and related to the task, installation can execute arbitrary code with the agent's local privileges; the declared oo-only tool allowance may limit execution if enforced but does not make these instructions safe.

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.
