Security audit
kalender-sync
Security checks for vulnerabilities and agentic risk
Overview
This is a disclosed calendar-connection skill that asks the user to grant calendar access and includes clear limits for writes and sync changes.
Install only if you want this assistant to access the calendars you select. Grant the minimum calendar detail and write permissions needed, store any ksa access key locally rather than in chat, and remember that created syncs may need to be paused or deleted separately from revoking assistant access.
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
