All four versions store the OpenAI API key in a .env file inside the project folder. The .gitignore files list .env, but some versions had keys committed before the ignore rule was in place.

Mitigation:

• Never commit .env files.
• Rotate any exposed API keys immediately.
• Consider using OS-level credential stores (e.g., keytar for Electron) instead of .env files.

The OpenAI API returns file paths as part of its JSON response. These paths are used directly to write files to disk. A malicious or crafted chat input could cause the LLM to return paths containing .. sequences, potentially writing files outside the intended output directory.

Affected files:

• v1-v2: modules/fileWriter.js
• v3: main/fileWriter.js
• v4: app/backend/file-system.js

Mitigation:

• Validate that all resolved output paths are within the expected output directory.
• Reject paths containing .., absolute paths, or paths starting with /.

Chat text is sent directly to the OpenAI API without sanitization. While this is the intended behavior (the LLM parses the chat), there is no validation of:

• Input size (could cause excessive API costs)
• Output size (could fill disk)
• File count (could create thousands of files)

Mitigation:

• Set maximum input length.
• Set maximum output file count and individual file size.
• Monitor API usage costs.

• v1-v3: Context isolation is enabled via preload scripts. Node integration is disabled in renderer by default (Electron defaults).
• v4: Same pattern. Additionally uses contextBridge properly.
• No versions enable nodeIntegration in renderer, which is correct.

v1-v2 use fs.writeFileSync which blocks the Electron main process. This is not a security issue per se, but could cause the app to become unresponsive with large outputs, which could be exploited for denial-of-service in shared environments.

If you discover a security issue, contact the repository owner directly. Do not open a public issue.
