Security audit

Agent Phone Call

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent phone-calling integration, but it under-discloses sensitive call recording/transcript handling and pushes broad activation, full transcript sharing, scheduled polling, and promotional sharing behavior.

Review this carefully before installing. It can place and answer calls through PollyReach, store an auth token locally, and expose phone numbers, transcripts, recordings, summaries, and caller details to a third-party service and to the agent chat. Do not use it for calls involving sensitive personal, financial, medical, legal, or confidential business information unless you understand consent, recording, retention, and caller-notice obligations. Avoid publicizing the assigned number or enabling scheduled polling without explicit control over what gets recorded and reported.

Missing User Warnings

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill encourages users to share phone numbers, make test calls, expose a dedicated number publicly, and rely on inbound-call handling, but does not present a prominent privacy warning before those actions. Because the service stores and returns transcripts, recordings, caller details, and summaries via a third-party platform, users may disclose their own and third parties' personal data without informed consent.

Exfiltration Commands

High
Category
Prompt Injection
Confidence
90% confidence
Finding

Instructions found that direct the agent to transmit conversation context or user data to external services.

Content

Scanner excerpt · SKILL.md (reported line 253)May include surrounding context.

md
- {"status":false,"task_id":"1f7aaf63-fab1-4f02-881c-22eba8ce4622","message":"Error message"}
**Features:**
- A status of true from the send API means PollyReach received the message. The actual result must be retrieved from query.sh.
- **Important:** After every call to send.sh return true, you **must** call query.sh. PollyReach will not proactively send messages to you — you must actively query for results.
- **Concurrency Limitation:** Polly can only handle one call at a time. If a call is in progress, subsequent send.sh requests will return `{"status":false,"message":"reason"}`. Agents should retry after the current call completes. Send requests one at a time.

External Transmission

Medium
Category
Data Exfiltration
Confidence
89% confidence
Finding

The skill is explicitly designed to send user instructions and call-related data to external PollyReach services and to persist an authentication token locally. While this is core functionality rather than covert exfiltration, it is still a real external transmission risk because sensitive user requests, phone numbers, transcripts, and recordings may leave the local environment.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger guidance is broad enough to activate on common phrases like 'make a call', 'help me contact', or 'help me book', which can cause the skill to engage in sensitive telephony workflows without sufficiently clear user intent. In this skill's context, activation can lead to account registration, external data transmission, and handling of phone numbers and call content, so over-triggering materially increases privacy and misuse risk.

External Transmission

Medium
Category
Data Exfiltration
Confidence
91% confidence
Finding

The registration step uses curl to send agent metadata to a remote API and initiates a trust relationship with an external service. In context this is expected behavior, but it is still security-relevant because it creates an account, transmits identifying data, and issues a bearer token that enables subsequent call operations and access to call records.

Ssd 3

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill mandates presenting full target information and line-by-line call transcripts after outbound calls. This creates unnecessary exposure of personal data, business details, and potentially sensitive third-party statements, exceeding what is needed for most task completion and increasing the chance of privacy breaches in logs, chat history, or shared sessions.

Content

Ssd 3

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The inbound-call workflow instructs the agent to always provide full caller information and complete transcripts, which is a strong plain-language data leakage pattern. Inbound callers may not expect their full conversation, number, and identity details to be broadly relayed or stored, and this is especially sensitive because the skill encourages public sharing of the number and automated answering.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

No manifest is available, so there is no stated purpose that justifies this script's capability to read a token from a local credentials file and use it in an authenticated request to an external service. Those behaviors materially expand the skill's power beyond a clearly bounded local utility and are not self-justifying without manifest context.

Missing User Warnings

For code files, network calls that transmit user or system data should have some visible disclosure unless clearly covered elsewhere; in this file there is no prompt, comment to the user, or runtime message describing the outbound request.
