Wappalyzer

Security checks for vulnerabilities and agentic risk

Overview

The Wappalyzer integration is coherent, but its fallback setup runs unverified remote code and does not explain the CLI’s broader changes to agent skills.

Review dependency setup before use. Prefer a separately reviewed, pinned CLI installation and check which agent skills it installs or updates. Installer contents could not be inspected. Requested domains and email addresses pass through OOMOL to Wappalyzer, and lookups may consume account credits.

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
98% confidence
Finding

The supplied command runs an Oomol installer rather than searching or reading Wappalyzer data. The declared description does not disclose this installation behavior, and the supplied code establishes no connection between the installer and Wappalyzer functionality. The downloaded script's further actions cannot be determined from this chunk.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
89% confidence
Finding

The supplied code consists solely of a login command and shows no connection to Wappalyzer. Authentication could support an implementation, but this chunk provides no evidence of that relationship and does not implement the declared functionality.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The curl-to-bash command executes the current contents of a remote installer without pinning or verifying them. HTTPS protects transport but not against a compromised publisher or hosting system, allowing arbitrary execution and potential access to local files and credentials; this is the same underlying installation issue identified by SQP-2, not an independent exploit.

Fallback setup executes remotely downloaded installation scripts without a security warning.

Medium
Category
Output Handling
Confidence
98% confidence
Finding

The fallback directs the agent to execute remotely retrieved shell or PowerShell code without inspection, integrity verification, or explicit installation approval. A compromised distribution endpoint or altered installer could execute arbitrary code with the agent's permissions; the missing-CLI condition limits exposure but does not make execution 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.
