Security audit

AI Interview Simulator

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent API guide for a remote interview service, but it handles resumes and interview results without enough privacy and retention guidance.

Review this skill before installing if you may upload resumes or retrieve interview results. Use it only if you trust Candaigo with resume contents, chat logs, participant information, and evaluation data; avoid uploading unnecessary personal details, protect the API key, and stop any polling loops when the interview session is done.

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

Finding

This endpoint retrieves full interview results including complete chat logs, participant information, and evaluations, which can contain sensitive personal and behavioral data. The skill documents access to this remote data without any privacy warning, minimization guidance, or caution about handling third-party participant information, increasing the risk of inappropriate collection or disclosure.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill instructs users to upload a resume file, which commonly contains sensitive personal data, to a remote service but does not provide any privacy, retention, consent, or third-party handling warning. This creates a real privacy/security risk because users may transmit PII without understanding where it is stored, how long it is retained, or who can access it.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The natural-language instructions throughout the skill are predominantly Chinese, while the document does not indicate that the skill is China-specific or offer alternative language support. This can violate language/locale policy when users are forced into a specific language without opt-in.
