Trust Assessment
remove-metadata-from-pdf received a trust score of 57/100, 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, 2 high, 2 medium, and 0 low severity. Key findings include Suspicious import: requests, Potential data exfiltration: file read + network send, Unpinned Python dependency version.
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 data exfiltration: file read + network send Function 'create_job' reads files and sends data over the network. This may indicate data exfiltration. Review this function to ensure file contents are not being sent to external servers. | Static | skills/crossservicesolutions/remove-metadata-from-pdf/scripts/remove-metadata-from-pdf.py:65 | |
| HIGH | Configurable API Base URL allows data exfiltration The skill allows the API base URL to be overridden by the `SOLUTIONS_BASE_URL` environment variable. If an attacker can control the environment where the skill runs, they can set this variable to a malicious server. This would cause all uploaded PDF files and the API key (sent in the Authorization header) to be exfiltrated to the attacker's controlled endpoint. While this is a common pattern for configurable services, it represents a significant data exfiltration risk if the execution environment is compromised or misconfigured. Restrict the ability to override `SOLUTIONS_BASE_URL` to a whitelist of trusted domains, or remove the override capability if the API endpoint is fixed. If overriding is necessary, ensure the environment where the skill runs is highly secured and that `SOLUTIONS_BASE_URL` cannot be manipulated by untrusted input or compromised processes. | LLM | scripts/remove-metadata-from-pdf.py:27 | |
| 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/crossservicesolutions/remove-metadata-from-pdf/scripts/remove-metadata-from-pdf.py:27 | |
| MEDIUM | Unpinned Python dependency version Requirement 'requests>=2.32.0' is not pinned to an exact version. Pin Python dependencies with '==<exact version>'. | Dependencies | skills/crossservicesolutions/remove-metadata-from-pdf/requirements.txt:1 |
