Security Findings5

Severity	Finding	Layer	Location
HIGH	Unsafe deserialization / dynamic eval Python builtins/import manipulation Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions.	Manifest	skills/rmanluo/zotero-skill/scripts/cli.py:68
HIGH	Unsafe deserialization / dynamic eval Python builtins/import manipulation Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions.	Manifest	skills/rmanluo/zotero-skill/scripts/cli.py:70
HIGH	Dangerous call: __import__() Call to '__import__()' detected in function '<module>'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives.	Static	skills/rmanluo/zotero-skill/scripts/cli.py:68
HIGH	Dangerous call: __import__() Call to '__import__()' detected in function '<module>'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives.	Static	skills/rmanluo/zotero-skill/scripts/cli.py:70
MEDIUM	Unpinned Python dependency The `scripts/install.sh` installs the `pyzotero` package without specifying a version. This can lead to non-reproducible builds and introduces a supply chain risk, as future versions of the package might contain breaking changes or security vulnerabilities that are automatically pulled into the environment. Pin the version of `pyzotero` in the `REQUIREMENTS` array, e.g., `REQUIREMENTS=(pyzotero==X.Y.Z)`. Alternatively, use a `requirements.txt` file with pinned versions.	LLM	scripts/install.sh:39
