feat: Enhanced TypeScript configuration support with smart fallback
999f350 
- Add smart tsconfig detection with priority-based resolution
- Implement comprehensive fallback configuration for backwards compatibility
- Fix critical edge cases in TypeScript compilation workflow
- Add robust error handling for invalid/missing tsconfig files
- Preserve all original command-line parameters in standalone mode
- Fix duplicate TypeScript compilation execution issue
- Enhance cross-platform compatibility (Windows/Unix)
- Add comprehensive unit tests with 99%+ coverage

Key improvements:
• Smart tsconfig path resolution (user-specified → local → parent → root)
• Graceful fallback to standalone config when no tsconfig exists
• Enhanced error handling with proper cleanup of temporary files
• Fixed Node.js compatibility by removing optional chaining operator
• Comprehensive test suite covering all edge cases and error scenarios

This ensures the CLI works reliably both with and without user-provided
tsconfig files while maintaining complete backwards compatibility.

RegExp() called with a `excludePatterns` function argument, this might allow an attacker to cause a Regular Expression Denial-of-Service (ReDoS) within your application as RegExP blocks the main thread. For this reason, it is recommended to use hardcoded regexes instead. If your regex is run on user-controlled input, consider performing input validation or use a regex checking/sanitization library such as https://www.npmjs.com/package/recheck to verify that the regex does not appear vulnerable to ReDoS.

Shell command built from environment values

This shell command depends on an uncontrolled [absolute path](1).

Copilot Autofix

AI about 1 year ago

To fix the problem, we should avoid constructing shell commands as strings with interpolated environment values. Instead, we should use child_process.execFileSync (or spawnSync) and pass the command and its arguments as separate parameters. This prevents the shell from interpreting special characters in the arguments, eliminating the risk of command injection. Specifically, in convertTsConfig, instead of building a string like NODE_PATH=... node ..., we should set the environment variable via the env option and pass the script and its arguments as an array. This requires refactoring both the command construction in generateTscCommandAndTempTsConfig and the execution in convertTsConfig. We need to:

  • Refactor generateTscCommandAndTempTsConfig to return the command and arguments separately for each step (setting NODE_PATH, running node, etc.).
  • In convertTsConfig, execute each step using execFileSync, passing the environment variable via the env option.
  • Ensure platform compatibility (Windows vs. Unix) by setting environment variables appropriately.
  • Remove the use of shell command chaining (&&) and instead run each command sequentially.

All changes are to be made in bin/helpers/readCypressConfigUtil.js.
