This pull request addresses a critical security vulnerability and introduces an administrative feature to improve the overall security and functionality of the disposable email service.
Key changes:
• Fixed a security flaw where using spaces or special characters as usernames could expose all incoming emails, potentially compromising user privacy.
• Implemented input validation to prevent unauthorized access through manipulated usernames.
• Added an "ADMIN_ACCESS_KEY" environment variable to allow authorized administrative access.
• When the correct admin key is provided as the username, the system now securely displays all emails, replicating the previous behavior for special characters but in a controlled manner.
These improvements significantly enhance the service's security posture while maintaining necessary administrative capabilities. I've thoroughly tested these changes to ensure they work as intended without introducing new issues.
I would greatly appreciate your review of these modifications. Please let me know if you need any clarification or have suggestions for further improvements. Thank you for considering this contribution to strengthen the project.
