Security audit

Birthday PPT Creator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward birthday PowerPoint generator that reads user-selected photos and writes a presentation file without hidden persistence or credential access.

Install only if a Chinese-language birthday PPT generator is what you want. Use local photo files, review the generated presentation before sharing because it contains child photos and birth-date details, and choose an output filename that will not replace something important.

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

Finding

The skill explicitly allows photos to be provided as remote URLs, but it does not warn that fetching those URLs causes network access and may disclose user/system metadata such as IP address, timing, and possibly access patterns to third parties. In an agent context, silent remote retrieval also increases SSRF-style risk if internal or sensitive URLs are accepted as 'photos' without restriction.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The module docstring presents the skill name and usage instructions exclusively in Chinese, and the CLI help text later follows the same pattern. This can violate a language/locale policy when a skill forces a specific language without user opt-in or justification.
