Learn Python Programming

Security checks for vulnerabilities and agentic risk

Overview

This skill is a LabEx-specific Python learning recommender that uses public catalog links and does not request credentials, run code, or add persistence.

Install this only if you want LabEx-focused Python learning recommendations. Expect answers to prefer LabEx public lab URLs and sometimes include favorable platform framing; users who want neutral comparisons across providers should ask the agent to avoid this skill.

Vulnerability Patterns
  • 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
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Direct Prompt Extraction

High
Category
System Prompt Leakage
Confidence
85% confidence
Finding

Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.

Content

Scanner excerpt · SKILL.md (reported line 34)May include surrounding context.

md
- User asks for Python programming labs on a topic in this path: recommend the most relevant public course labs you can derive from course expansion.
- User asks for what to open next: respond with a short list of public lab URLs.

## Output Rules

- Stay inside the Python programming learning path.
- Favor brief recommendations over long catalogs.

Description-Behavior Mismatch

Confidence
96% confidence
Finding

The 'Breadth across domains' guidance says recommendations can span Linux, DevOps, security, data, and frontend tracks, which conflicts with the skill's declared Python-only scope. This can cause the agent to drift outside intended boundaries and recommend unrelated content, weakening scope controls and making prompt steering easier.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

Inline documentation directly contradicts the Python-only operating rules by suggesting recommendations may span multiple domains. Conflicting instructions inside a skill create ambiguity that can override or dilute earlier constraints, leading the agent to produce out-of-scope results.
