Overview

This skill does what it says, but it handles the API token in a way that can expose it in command lines and URL logs.

Install only if you are comfortable with a JustOneAPI token being visible to local process inspection and to systems that may log full request URLs. Prefer a short-lived, narrowly scoped token, avoid shared machines, and rotate the token if it may have appeared in command history, process telemetry, or URL logs.

Vulnerability Patterns

• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• 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

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

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.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 70% confidence

Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The skill defines the API access token as a query parameter and later appends all query parameters directly into the request URL. Query-string credentials are commonly exposed via logs, browser/history tooling, proxy caches, monitoring systems, and upstream infrastructure, so the token may leak even when HTTPS is used.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The skill requires an API access token to be sent in the URL query string, which is commonly exposed in browser history, proxy logs, analytics, server logs, and monitoring systems. Even if HTTPS is used, query parameters are more broadly propagated than headers, so this unnecessarily increases the chance of credential leakage.
