Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| MEDIUM | Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated. | Static | skills/killgfat/pyzotero/SKILL.md:37 | |
| MEDIUM | Unpinned dependency in installation instructions The skill's manifest and installation instructions recommend installing the `pyzotero[cli]` package without specifying a version. This can lead to supply chain vulnerabilities if a malicious or vulnerable version of the package is published in the future, as users would automatically install the latest version. It is best practice to pin dependencies to specific, known-good versions. Pin the dependency to a specific, known-good version (e.g., `pyzotero[cli]==X.Y.Z`) in both the manifest and all installation instructions. Regularly update the pinned version after verifying new releases. | LLM | SKILL.md:10 |
