Trust Assessment
cloudflare-dns-updater received a trust score of 70/100, placing it in the Caution category. This skill has some security considerations that users should review before deployment.
SkillShield's automated analysis identified 4 findings: 0 critical, 1 high, 2 medium, and 1 low severity. Key findings include Suspicious import: requests, Unpinned Python dependency version, Potential Command Injection via Unsanitized User Input to Shell Execution.
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 Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Potential Command Injection via Unsanitized User Input to Shell Execution The skill explicitly instructs the AI to 'Construct Command' and 'Execute Command' using an `exec` tool, with arguments (`--zone`, `--record`, `--ip`) derived from user input. The documentation does not provide any guidance or mechanism for the AI to sanitize or escape user-provided values before incorporating them into the shell command string. This creates a high risk of command injection, where a malicious user could embed arbitrary shell commands within their input (e.g., `myzone.com; rm -rf /`) which would then be executed by the underlying system when the AI constructs and runs the command. Instruct the AI to strictly sanitize or escape all user-provided arguments before constructing the shell command. Ideally, use a safer execution mechanism that passes arguments directly to the Python script without shell interpretation, or provide explicit instructions for shell escaping (e.g., using `shlex.quote` if Python is used for command construction). | LLM | SKILL.md:48 | |
| MEDIUM | Suspicious import: requests Import of 'requests' 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/xieyuanqing/cloudflare-dns-updater/scripts/update-record.py:6 | |
| MEDIUM | Unpinned Python dependency version Requirement 'requests' is not pinned to an exact version. Pin Python dependencies with '==<exact version>'. | Dependencies | skills/xieyuanqing/cloudflare-dns-updater/requirements.txt:1 | |
| LOW | Unpinned Dependency in requirements.txt The `requirements.txt` file specifies the `requests` package without a version pin. This can lead to non-deterministic builds and potential compatibility issues or unexpected behavior if a new, incompatible version of the dependency is released. While not a direct security vulnerability, it introduces a minor supply chain risk. Pin the dependency to a specific version (e.g., `requests==2.28.1`) or use a version range (e.g., `requests>=2.28.1,<3.0.0`) to ensure consistent and predictable behavior across deployments. | LLM | requirements.txt:1 |
