🚨 Severity: HIGH 💡 Vulnerability: 1. Critical SyntaxError in `create_folder` prevented script execution. 2. Missing validation on `folder_url` allowed potential SSRF/MITM via HTTP. 3. Missing validation on `profile_id` allowed potential injection/path traversal in API calls. 🎯 Impact: - Script was unusable due to syntax error. - Attackers could potentially redirect traffic or access internal network resources if the script was run with malicious arguments. 🔧 Fix: - Corrected `_api_post` call arguments in `create_folder`. - Added `validate_folder_url` to enforce HTTPS. - Added `validate_profile_id` to enforce alphanumeric characters. ✅ Verification: - Verified `main.py` compiles successfully. - Verified validation logic with unit tests (passed).

Pull request overview
This PR addresses a critical syntax error in the create_folder function and adds security hardening through input validation for folder_url and profile_id parameters to prevent SSRF and injection attacks.
- Fixed syntax error where a positional argument was placed after keyword arguments in
_api_postcall - Added validation functions to check folder URLs (HTTPS protocol) and profile IDs (alphanumeric characters only)
- Integrated validation checks at appropriate points in the sync workflow

The folder URL validation only checks for the HTTPS protocol but doesn't validate the host. This could still allow SSRF attacks against internal services accessible via HTTPS (e.g., "https://localhost:8080/admin" or "https://192.168.1.1/"). Consider adding an allowlist of trusted domains (e.g., only allowing github.com and githubusercontent.com) or at minimum blocking private IP ranges and localhost.

…ions Added unit tests to `tests/test_fix_env.py` and `tests/test_disk_cache.py` that pre-create the `.tmp` files as symlinks. These tests verify the `os.O_EXCL` error handling safely deletes the symlink and exclusively creates the new temp file without following the symlink.
