SkillShield's automated analysis identified 2 findings: 0 critical, 1 high, 1 medium, and 0 low severity. Key findings include Suspicious import: urllib.request, Potential YouTrack API Token Exfiltration via Malicious base_url.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Potential YouTrack API Token Exfiltration via Malicious base_url The `YouTrackAPI` class in `scripts/youtrack_api.py` constructs API requests using a user-provided `base_url` and includes the `YOUTRACK_TOKEN` in the `Authorization` header. If an attacker can manipulate the `base_url` argument (e.g., through prompt injection to the LLM that invokes this skill), they could direct the skill to send the `YOUTRACK_TOKEN` to an arbitrary, attacker-controlled server, leading to credential harvesting and data exfiltration. Implement strict validation for the `base_url` parameter to ensure it points only to trusted YouTrack instances. This could involve a whitelist of allowed domains or a mechanism to verify the URL's authenticity before making requests. If the skill is intended to only work with a single, fixed YouTrack instance, hardcode the `base_url` or retrieve it from a secure configuration, rather than accepting it as a dynamic input. | LLM | scripts/youtrack_api.py:40 | |
| MEDIUM | Suspicious import: urllib.request Import of 'urllib.request' detected. This module provides network or low-level system access. Verify this import is necessary. Network and system modules in skill code may indicate data exfiltration. | Static | skills/digisal/youtrack-digisal/scripts/youtrack_api.py:13 |
