Security audit

Flash Sale Designer

Security checks for vulnerabilities and agentic risk

Overview

This is a non-executable marketing planning skill whose guidance is disclosed and aligned with designing flash sales.

Before using the templates, confirm inventory, cart, sales, times, SMS opt-in language, and promotional claims against live business data and the laws/platform rules for the audience region.

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
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

## Threshold-Based Visibility Rules

Missing User Warnings

Confidence
91% confidence
Finding

These templates encourage scarcity and social-proof claims such as units left, carts active, and units sold without clearly requiring that the numbers be accurate and verifiable at runtime. In a flash-sale skill, that omission is risky because operators may fill in persuasive but fabricated values, creating deceptive marketing and compliance exposure.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
87% confidence
Finding

The templates repeatedly hard-code sale times in EST, starting with the teaser copy, without offering localization or noting that the timezone should be adapted to the recipient. This can violate a language/locale policy when content is sent to audiences outside that locale without explicit opt-in or a region-specific justification.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The file directs copywriters to 'Always name a specific end time in the local timezone of your primary audience,' and later examples hard-code EST. This can impose a locale choice on end users without offering a language/locale choice or documenting a justified regional limitation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
86% confidence
Finding

The SMS and social templates include fixed 'EST' references in natural-language content. Because the file does not clearly limit itself to an EST-only audience or provide locale alternatives, these examples can encourage forcing a specific locale without user opt-in.
