Generate Daily Sports Update

• Outcome: Review
• Latest audit: Sep 11, 2026 · 4:33 AM UTC
• Version: 1.0.0

Overview

The skill has a clear sports-reporting purpose, but it asks the agent to run unaudited local Python code and dependencies with Notion credentials.

Install only if you already trust the `sports-science-daily` checkout you will run. Review `daily_sports_update.py` and `requirements.txt`, use a dedicated virtual environment, pin and verify dependencies, run from an owned directory, and restrict the Notion token to the minimum page and permissions needed.

Vulnerability Patterns

• Tool Hijacking and Spoofing: Modifies or replaces tools so legitimate-looking calls execute attacker logic
• 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 Details

File Location: SKILL.md, lines 20–38
Vulnerability Type: Untrusted relative-path code execution and insecure dependency loading
Risk Level: High

Vulnerable Code

markdown

- **Python 3**: Requires `python3` to be installed.
- **Dependencies**: The required Python packages defined in `requirements.txt` must be installed (`pip3 install -r requirements.txt`).
- **Environment Variables**:
  - `NOTION_TOKEN`: The integration token for Notion API.
  - `NOTION_PAGE_ID`: The ID of the Notion page to sync the daily update to.
- **Tools Needed**: You must have access to the `run_command` tool to execute the script in a bash terminal.

## Instructions

1.  **Locate the Script**:
    The script `daily_sports_update.py` is located in the user's sports-science-daily directory. You should first ensure you are in the correct working directory.

2.  **Run the update**:
    Use the `run_command` tool to execute the python script.

    ```bash
    python3 daily_sports_update.py --days 2
    ```

Technical Analysis

The Skill instructs the Agent to locate an unspecified user-controlled directory and execute daily_sports_update.py using a relative path. It also refers to installing dependencies from a relative-path requirements.txt. Neither file is included in the audited package, and the instructions provide no canonical path, integrity hash, signature, trusted repository revision, or other provenance validation.

Relative-path resolution makes the effective executable depend on the Agent's current working directory. If an attacker can create or replace daily_sports_update.py in the selected directory, python3 will execute that file with the Agent's operating-system privileges. Likewise, an attacker-controlled requirements.txt could introduce malicious or substituted packages; package installation can execute package build or installation logic.

Remediation

Remediation Suggestions

1. Bundle daily_sports_update.py and the dependency manifest inside the reviewed Skill package rather than locating them in an unspecified user directory.
2. Resolve the script from a canonical, immutable absolute path derived from the verified Skill installation directory. Do not execute a same-named file merely because it exists in the current working directory.
3. Authenticate executable content before use through signed releases, pinned repository revisions, or cryptographic hashes obtained from a trusted source.
4. Pin every dependency to an exact reviewed version and require hashes, such as with pip install --require-hashes -r requirements.txt.
5. Install dependencies into a dedicated virtual environment rather than the user's global Python environment.
6. Disable unnecessary package installation features and avoid untrusted indexes. Explicitly configure approved package repositories and review packages that require build-time execution.
7. Pass only the environment variables required by the verified script. Avoid exposing unrelated credentials from the Agent's broader environment.
8. Restrict the Notion integration token to only the target page and minimum necessary API capabilities. Support token rotation if compromise is suspected.
9. Apply outbound network restrictions so the process can contact only documented and necessary endpoints, including the approved Notion and research-feed hosts.
10. Validate directory ownership and permissions before execution, and reject scripts or manifests writable by untrusted users.
11. Include the actual implementation and dependency files in future audits so endpoint use, file access, command construction, secret handling, and data collection can be verified.

Vulnerability Patterns

• Rogue Agent: Self-Modification, Session Persistence
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access

Findings (3)

Self-Modification

High

• Category: Rogue Agent
• Confidence: 85% confidence

Finding

Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.

# Generate Daily Sports Update

This skill runs the `daily_sports_update.py` script to fetch the latest sports science research and wearable tech news. It automatically handles deduplication, so you can run it frequently without worrying about seeing the same content twice.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The documented output file name and terminal success condition include Chinese text (运动科学日报, 没有发现新内容) with no indication that language is configurable or chosen by the user. This creates a locale policy concern because the skill appears to assume a specific language by default rather than offering or documenting user choice.

Content

No source excerpt is available for this finding.

Vague Triggers

Low

• Category: Not specified by scanner
• Confidence: 89% confidence

Finding

The manifest description says the skill 'Runs the sports science crawler to generate a daily report, sync to Notion, and prevent duplicate content' but does not provide any explicit invocation phrases, constraints, or negative examples. For a user-invocable skill, this can make activation scope ambiguous and increase the chance of unintended matching against general requests about daily reports or sports updates.
