This coursework project is maintained as a single current version:

For coursework review, report security issues through the appropriate Singapore Polytechnic class or module channel. If this project is later published, report privately to the repository maintainer before opening a public issue.

Please include:

• A short description of the issue.
• Steps to reproduce it.
• Affected files or commands.
• Any known impact on user files or generated outputs.

CI runs:

• bandit for Python static security analysis.
• pip-audit for runtime dependency vulnerability checks.

The app reads and writes user-provided local file paths. Treat input files as untrusted text and avoid running the program on files from unknown sources without inspecting them first.
