Football Prediction Optimized

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its football-prediction purpose, but it sends user data and a DeepSeek API credential over an unvalidated configurable API endpoint.

Review before installing. Use this only if you are comfortable sending match feature text to DeepSeek or a configured compatible endpoint, avoid proprietary betting/account data in inputs, and do not set DEEPSEEK_BASE_URL unless it is a trusted HTTPS endpoint meant to receive that credential. Treat predictions as advisory, not as validated financial advice.

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Findings (7)

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 95% confidence
Finding: The skill advertises executable capabilities involving environment access, file I/O, and network use, but does not declare any explicit tool scope or permissions boundary. This creates an authorization ambiguity where the agent may invoke broader capabilities than users expect, increasing the risk of unintended data access, local file handling, and exfiltration to the external DeepSeek API.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The automatic trigger phrases are broad enough to match normal sports-analysis requests, which can cause the skill to run unexpectedly without clear user intent to invoke this specific workflow. Because the skill performs model/network operations and may process user-provided match data externally, overbroad triggering increases the chance of unintended data handling and opaque agent behavior.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 97% confidence
Finding: The skill documentation states that it sends data to the DeepSeek API, but it does not clearly warn users that match features and possibly derived user-supplied content will be transmitted to a third-party external service. This undermines informed consent and can lead to privacy or compliance issues, especially if inputs contain proprietary betting data, account-linked information, or other sensitive context.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The module docstring, CLI description, help text, logs, and prompt instructions are all written exclusively in Chinese, which imposes a specific language on users. There is no indication that the skill is region-specific or that users may opt into another language, so this is a natural-language locale policy concern.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 81% confidence
Finding: All user-facing documentation and examples in the file are presented in Chinese, and the skill does not mention that it is Chinese-only or provide any user language choice. This can constitute a language-policy issue because the skill effectively forces a specific language without explicit opt-in or justification.
Content: No source excerpt is available for this finding.

Unpinned Dependencies

Low

Category: Supply Chain
Confidence: 96% confidence
Finding: The dependency is specified as requests>=2.28.0, which allows installation of any future version and does not ensure a reproducible or reviewed package set. This increases supply-chain risk and makes it impossible to guarantee that a known-safe version is used across environments.
Content: Scanner excerpt · requirements.txt (reported line 1)May include surrounding context.
text
requests>=2.28.0

Unverifiable Dependency: requests has 16 known advisory(ies) (CVE-2014-1830 (Exposure of Sensitive Information to an Unauthorized Actor in Requests); CVE-2024-47081 (Requests vulnerable to .netrc credentials leak via malicious URLs); CVE-2024-35195 (Requests `Session` object does not verify requests after making first request wi) +13 more), but the manifest does not pin a version, so it is unknown whether the installed release is affected

Low

Category: Supply Chain
Confidence: 93% confidence
Finding: Because requests is not pinned, the manifest does not show whether deployment will use a version affected by known security advisories. This creates uncertainty around exposure to published requests vulnerabilities and weakens the ability to audit or reliably secure the skill's runtime dependencies.
