Security audit

WPS PowerPoint

Security checks for vulnerabilities and agentic risk

Overview

This PPTX helper is purpose-aligned and shows no malicious behavior, but its package appears incomplete and may not work as intended.

Install only if you are comfortable with a Chinese-language PPTX workflow that reads and writes presentation files. Expect functional issues unless the missing referenced guide files are supplied, and check output filenames to avoid accidental overwrite.

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

Findings (2)

Natural-Language Policy Violations

Medium
Confidence
88% confidence
Finding
The natural-language description and trigger guidance are presented in Chinese and do not indicate that users may choose another language or that the skill is intentionally locale-specific. This can constitute a language/locale policy issue because the skill appears to impose a specific language without opt-in or justification.

Missing User Warnings

Low
Confidence
91% confidence
Finding
For a markdown skill file, file-writing behavior that affects user data should be disclosed clearly. These lines instruct the agent to save an edited `.pptx` file to an output path, but the description does not provide any warning or note about overwriting, creating output artifacts, or where files will be written.
