Security audit

UXLens

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward UXLens website-audit helper, with expected remote API use and no local executable or persistence behavior.

Before installing, understand that audits are performed through UXLens, so URLs you submit and any pages reached during full-site crawling should be treated as shared with a third-party service. Avoid private, internal, staging, localhost, authenticated, or client-sensitive sites unless you have authorization and are comfortable with that exposure. Protect the UXLENS_API_KEY like any other API credential.

A.I.G

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

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill encourages users to submit arbitrary URLs for analysis and explicitly supports full-site crawling, but it does not clearly warn that the target URL, fetched page contents, and potentially broader site data will be transmitted to and processed by an external third-party service. In agent workflows, this can lead to unintentional disclosure of internal, staging, localhost-accessible, or otherwise sensitive web content because the operator may assume analysis is local or confined to minimal metadata.
