Security audit
Buffer
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed Buffer integration that uses Maton-managed authentication and includes clear approval requirements for account connections, publishing actions, hosted functions, and persistent triggers.
Install only if you are comfortable connecting Buffer through Maton. Review any requested Buffer write, function deployment, trigger, or destination carefully, because posts can be published publicly and triggers or destinations can continue running until removed. Prefer OAuth login over API keys and do not allow credentials to be printed, stored in files, or forwarded to third-party URLs.
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
