[WIP] Check code for CVE-2026-22184 vulnerability

[Copilot]

Investigation: CVE-2026-22184 Impact on knime-python

Analysis Complete

• Research CVE-2026-22184 vulnerability details
• Identify zlib usage in repository (pixi.lock shows zlib 1.3.1)
• Determine actual risk to repository
• Verify if untgz utility is present (it is NOT)
• Document findings in security documentation
• Update zlib to 1.3.1.3+ as preventive measure (if needed)
• Add security check to CI/CD pipeline (if needed)

Key Findings

The repository is NOT meaningfully affected by CVE-2026-22184:

• Conda-forge zlib packages only include core library, not the vulnerable untgz contrib utility
• No direct usage of zlib in Python/Java code
• zlib is only a transitive dependency through Arrow and other libraries
• The vulnerability only affects the standalone untgz demonstration tool, not the library

Recommended Actions

While not strictly necessary, should consider:

1. Documenting this CVE assessment for future reference
2. Optionally upgrading to zlib 1.3.1.3+ when available in conda-forge
3. Adding dependency vulnerability scanning to CI/CD
