• Version: 0.1.1

Overview

This skill is a narrowly scoped Go helper for using an unofficial Cal.com API client, with its network and credential use disclosed and aligned to scheduling tasks.

Install only if you intend to use an unofficial Go client for Cal.com. Treat `CALCOM_API_KEY` as sensitive, review any code that creates, reschedules, cancels, or edits bookings and scheduling resources, and confirm the configured Cal.com host before sending account data.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Findings (4)

Credential Access

High

• Category: Privilege Escalation
• Confidence: 70% confidence

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Content

Scanner excerpt · references/setup.md (reported line 8)May include surrounding context.

## Requirements

- Go 1.26.9 or newer, per `go.mod`.
- A Cal.com API key or supported access token, exported as `CALCOM_API_KEY`. Endpoint access depends on the account plan and permissions.

## Install

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 50% confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

## Base URL

The spec declares no server URL. Pass `https://api.cal.com` to `calcom.NewClientWithResponses`. The [profile docs](https://cal.com/docs/api-reference/v2/me/get-my-profile) show `https://api.cal.com/v2/me`. Generated paths already contain `/v2`, so use the host without that suffix. Pass another host for a configured deployment or local test server.

## Auth and API versions

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 75% confidence

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

## Rate limits

Handle HTTP 429 with bounded backoff. The generated client does not automatically retry or pace requests. Avoid retrying booking mutations without checking their result and the endpoint's idempotency behavior.

Missing User Warnings

Low

• Category: Not specified by scanner
• Confidence: 81% confidence

Finding

This markdown file instructs users to export CALCOM_API_KEY, which is a sensitive credential, but provides no caution about protecting the key, avoiding committing it to source control, or using secure secret storage. For documentation that directs users to handle credentials, a brief warning helps reduce accidental exposure.
