Security checks for vulnerabilities and agentic risk
Overview
This skill is a coherent poster-building workflow with expected file, web, and rendering steps, and I found no hidden persistence, credential access, destructive behavior, or exfiltration instructions.
Before installing, be comfortable with the agent using local paper or LaTeX files you provide, browsing public venue/project/affiliation pages for current details and logos, and writing a poster output folder. Review generated claim audits and asset provenance, especially for copyrighted logos or figures.
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
- 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
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
