• Latest audit: Sep 11, 2026 · 8:40 PM UTC
• Version: 1.0.0

Overview

This skill is labeled as GitHub tooling but mainly instructs agents to use a broad third-party AI and communications API, creating a real risk of unexpected data sharing and side effects.

Review before installing. Use this only if you intend to give an agent access to the SkillBoss/HeyBossAI API, not just GitHub. Do not send secrets, private repository data, personal documents, audio, images, email content, or phone numbers through it unless you are comfortable with that third-party processing. Require explicit confirmation before any email, batch email, SMS, or OTP action.

A.I.G

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

Vulnerable Code

yaml

name: github
description: "Interact with GitHub using the gh CLI for issues, PRs, CI runs, and advanced queries. And also 50+ models for image generation, video generation, text-to-speech, speech-to-text, music, chat, web search, document parsing, email, and SMS."

Technical Analysis

The skill is registered under the generic and trusted-looking name github, and its description leads with GitHub and gh CLI functionality. However, the reviewed instructions do not provide a GitHub workflow. Instead, they direct the agent to use the SkillBoss/HeyBossAI model aggregation API at https://api.heybossai.com/v1.

This metadata-to-behavior mismatch may cause an agent or user to select the skill for GitHub operations while unknowingly loading instructions for an unrelated external service. Those instructions support transmitting prompts, documents, audio, images, email content, telephone numbers, and other supplied information to the external API. They also expose side-effecting email and SMS functions.

The audit did not find evidence that the skill automatically steals credentials, overrides safety constraints, executes downloaded code, or establishes persistence. Therefore, this finding is classified as misleading metadata rather than instruction hijacking or malicious code execution.

Attack Path

1. A user or agent searches for and selects a skill named github, expecting GitHub or gh CLI functionality.
2. The skill loads instructions whose actual operational target is api.heybossai.com.
3. The agent follows those instructions and submits user-supplied content to that external service.
4. If the requested workflow involves communication features, the agent may also initiate email or SMS operations that the user did not reasonably associate with a ...[truncated 775 chars]

Remediation Suggestions

1. Rename the skill from github to an accurate identifier such as skillboss or heybossai-model-gateway.
2. Remove the unsupported claim that the skill interacts with GitHub through the gh CLI, or implement and clearly separate the claimed GitHub functionality.
3. State prominently that user content is transmitted to api.heybossai.com and may be processed by downstream model providers.
4. Identify sensitive data classes that should not be submitted without explicit authorization, including credentials, private documents, personal audio, email addresses, and phone numbers.
5. Require explicit user confirmation immediately before side-effecting email, batch email, SMS, or OTP operations.
6. Document billing implications and recommend a scoped, limited-credit API credential where supported.
7. Document the provenance and installation requirements of the referenced run.mjs executable, or remove those examples and consistently use the documented curl interface.

Findings (36)

Description-Behavior Mismatch

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The skill is presented as a GitHub/gh CLI integration, but the body actually documents an unrelated third-party AI aggregation service with broad external-action capabilities. This mismatch is dangerous because it can cause operators or agents to invoke non-GitHub network actions under false pretenses, including sending user data to external providers and enabling capabilities far beyond the declared purpose.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

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

Finding

The file documents broad non-GitHub capabilities including image/video generation, TTS/STT, music, document parsing, and web search, none of which align with a GitHub interaction skill. This scope inflation increases attack surface and creates a deceptive capability envelope that can route prompts, files, audio, and documents to external services without users expecting it.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

A skill framed as GitHub tooling includes email sending and SMS/OTP operations, which materially expands it into external communications and identity-verification workflows. In context, these capabilities are unjustified and could be abused for phishing, spam, account-verification abuse, or covert data exfiltration through out-of-band channels.

Content

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 70% confidence

Finding

The skill declares a third-party API base URL and bearer-token authentication, establishing that actions will occur outside the local/GitHub context. On its own this is not inherently malicious, but in a deceptively named skill it obscures trust boundaries and where data will be sent.

Finding

This example performs outbound network communication to a third-party API using a bearer token. While model-list retrieval is not inherently malicious, in this mislabeled skill it contributes to undisclosed external dependency use and can normalize sending credentials and subsequent data to a non-GitHub service.

Missing User Warnings

Medium

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

Finding

The examples repeatedly send prompts, documents, audio, images, phone numbers, and email content to external APIs, but provide no privacy, retention, or data-handling warnings. This is dangerous because users may unknowingly submit sensitive repository content, personal data, or confidential files to third-party services with unknown storage and sharing practices.

Medium

• Category: Data Exfiltration

• Category: Data Exfiltration
• Confidence: 87% confidence

Finding

This image-to-video example transmits a user-provided image URL and prompt to an external service, disclosing both content and metadata to a third party. Because the skill is misbranded as GitHub tooling, the trust-boundary violation is more dangerous than a clearly labeled media skill would be.
