Vulnerability Description
I have identified critical security misconfigurations in the .env.example file provided in the repository.

1. Remote Code Execution (RCE) Risk:
   The AP_EXECUTION_MODE is set to "UNSANDBOXED" by default. If a developer or user deploys this application using the default configuration, it exposes the host server to arbitrary code execution risks via workflow automation features.

2. Hardcoded Cryptographic Secrets:
   Sensitive keys such as AP_API_KEY, AP_ENCRYPTION_KEY, AP_JWT_SECRET, and database credentials are hardcoded with actual values instead of placeholders.

Impact Assessment

• Critical (RCE): Potential for full server takeover if the execution mode is not sandboxed.
• High (Data Leak): Hardcoded encryption keys jeopardize the confidentiality of user data and sessions.

Proposed Solution
I have prepared a fix that:

• Changes the default execution mode to SANDBOXED.
• Replaces all hardcoded secrets with safe placeholders (e.g., CHANGE_ME_IN_PRODUCTION).
