Voice Call

Security checks for vulnerabilities and agentic risk

Overview

This is a narrow voice-call skill with expected real-world calling risks, but no hidden code, persistence, or deceptive behavior was found.

Install only if you intend agents to place or manage voice calls. Use the mock provider for testing, and require explicit confirmation before any non-mock call to a real number because phone numbers and call messages may be sent to the configured telephony provider and may create billing charges.

A.I.G

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

Finding

The skill enables agent-initiated outbound voice calls through external providers, but the documentation does not clearly warn users that using it may contact real phone numbers, incur charges, and transmit call content to third-party telephony services. In an agent environment, that omission is security-relevant because users may invoke the skill without understanding the external side effects or privacy implications.
