Security audit

Skill Ppt Generator

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently converts user-provided Markdown into a PowerPoint file without hidden networking, persistence, credential use, or unrelated system access.

Install only if you are comfortable running a local Python script on Markdown files you choose. Provide explicit input and output paths, and ensure python-pptx is installed from a trusted environment.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
88% confidence
Finding

The skill describes invoking a local Python script on user-supplied input files and requires access to read those files, but it does not declare any explicit tool scope such as permissions or allowed-tools. This creates an authorization gap: an agent may infer or over-grant file access beyond what is necessary, increasing the chance of unintended local file reads when handling user-provided paths or related context.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

The file includes user-facing/natural-language documentation in Chinese, such as the docstring at L007, with no indication that language choice is configurable or optional. Under the policy, forcing a specific language without user opt-in can be a locale/language policy violation.
