AI Phone

Security checks for vulnerabilities and agentic risk

Overview

This AI phone skill is purpose-aligned but needs Review because it handles sensitive calls through a third party, stores a powerful bearer token weakly, and adds mandatory promotion/referral behavior outside the core phone task.

Review before installing. Use only if you are comfortable sending phone numbers, call content, transcripts, recordings, summaries, and account metadata to PollyReach. Protect the token file as a secret, avoid printing it into chat or logs, require clear human approval before calls or scheduled polling, and do not forward the remote SKILL.md installation message to other agents as executable instructions.

Bearer Token Is Printed Into Agent Context and Stored Without Required Permission Hardening

Content
View full analysis
/dev/null ``` ``` The storage instructions do not specify restrictive directory or file permissions: ```markdown Save to `~/.config/PollyReach/key.json`: ```json { "token": "xxx", "agent_name": "YourAgentName" } ``` ``` ### Technical Analysis The credential is a bearer token used by the scripts in the `Authorization` HTTP header. Anyone who obtains it can attempt to authenticate as the associated PollyReach agent. Using `cat` to check whether a credential exists unnecessarily emits the complete JSON document into the agent's tool context. That output may subsequently be retained in tool logs, conversation records, debugging output, or other observability systems. The storage procedure also fails to require mode `0700` for the containing directory and mode `0600` for the credential file. Actual exposure depends on the process umask and the method used to create the file, but the documented procedure does not enforce least-privilege access. ### Attack Path 1. The agent follows the documented Step 0 credential check. 2. `cat` prints the complete `key.json`, including the bearer token. 3. The token becomes part of tool output or associated logs. 4. A party with access to those records copies the token. 5. The party submits the token to PollyReach API endpoints through an `Authorization: Bearer` header. 6. Subject to server-side authorization, the party can impersonate the associated agent and access or initiate account operations. A local variant is possible if the file is created with permissions that allow another local account to read i ...[truncated 646 chars]

0' \ "$HOME/.config/PollyReach/key.json" >/dev/null ``` 3. Create the credential directory and file with restrictive permissions: ```bash install -d -m 700 "$HOME/.config/PollyReach" umask 077 ``` 4. Write credentials atomically through a temporary file created inside the protected directory, apply mode `0600`, and then rename it into place. 5. Avoid passing tokens through command-line arguments, standard output, or diagnostic messages. 6. Redact authorization headers and token fields from application, shell, proxy, and CI logs. 7. Provide token revocation and rotation procedures for suspected disclosure. 8. Prefer an operating-system credential store when available. ]]>

Missing User Warnings

Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill promotes call screening, transcription, recordings, summaries, and logs without a clear warning that highly sensitive personal and business data will be collected, transmitted to PollyReach, stored, and potentially exposed through recordings and dashboards. Users may unknowingly route confidential conversations through a third party without informed consent or awareness of retention/sharing implications. In a telephony skill, that omission creates significant privacy and compliance risk.

- {"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
92% confidence
Finding

The skill is designed to send data to external PollyReach services, and the documented capabilities include transmitting phone numbers, prompts, task details, transcripts, and call metadata off-host. External transmission is inherent to the feature set, but it still creates a real data exposure boundary because sensitive communications are handled by a third party. Given the phone/recording context, this is materially more dangerous than ordinary low-sensitivity API usage.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

The skill's activation/use guidance is broad and lacks exclusion boundaries, making it easy for an agent to invoke it in situations involving sensitive communications, regulated interactions, or unintended outbound contact. That can lead to over-collection and unnecessary transmission of phone numbers, transcripts, and call content to the third-party service. For a phone automation skill, unclear triggering conditions increase the chance of accidental privacy-impacting actions.

External Transmission

Category
Data Exfiltration
Confidence
95% confidence
Finding

The registration flow sends identifying agent information and later enables broader transmission of call instructions and communication data to an external API endpoint. While expected for this service, it is still a true security/privacy concern because users may not realize they are onboarding to a third-party communications processor with access to sensitive call content and metadata. The context makes the impact more serious due to recordings, transcripts, and phone-based interactions.

Missing User Warnings

Confidence
98% confidence
Finding

The instructions tell users to save the token locally but do not clearly label it as a secret credential that grants account access and control over calls, call records, and account state. If the file is read by another local user, included in backups, or exposed through logs or tooling, an attacker could take over the PollyReach account and access sensitive communications. The credential sensitivity is heightened because the same token is reused for multiple APIs.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The documentation gives conflicting guidance about whether incoming call information is proactively pushed or must be actively polled. In a communications workflow, this ambiguity can cause operators to assume notifications will arrive automatically and miss calls, voicemails, or follow-up actions. Because the skill handles potentially time-sensitive phone traffic, inconsistent behavior materially increases operational and privacy risk.

This shell script accesses a credential file to extract a bearer token and then sends that token to a remote API via curl. While the script has error messages for missing dependencies and files, it does not provide any user-facing warning, confirmation, or explanatory comment that the credential will be used in an outbound network request.

The comment at L14 states 'never pass token as CLI arg', implying the token will not appear in command-line arguments. However, the curl invocation at L28-L30 includes the bearer token directly in the process arguments via the Authorization header, which contradicts that stated intent.
