Security audit
Postsyncer
Security checks for vulnerabilities and agentic risk
Overview
This skill is a small, disclosed PostSyncer helper that documents user-run commands for listing workspaces/posts and creating a basic social post with an API key.
Install only if you intend to let your agent use your PostSyncer account. Treat create-post as an account-impacting action and review workspace IDs and post text before running it; also verify the postsyncer CLI source because this skill only documents CLI usage and does not include the CLI itself.
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
