Symfony running in dev mode
Description
The Symfony web application is currently configured to run in development mode (dev) rather than production mode (prod). Development mode is designed for local debugging and provides verbose error reporting, including detailed stack traces, configuration details, and internal application state information. This configuration is controlled by the APP_ENV environment variable and should never be enabled on production servers, as it exposes sensitive technical information that can aid attackers in identifying vulnerabilities and understanding the application's internal structure.
Remediation
Switch the Symfony application to production mode by updating the APP_ENV environment variable to prod. Follow these steps:
1. Locate your environment configuration file (.env or .env.local) in the application root directory.
2. Set the APP_ENV variable to prod:
# .env.local (recommended for production-specific settings) APP_ENV=prod APP_DEBUG=0
3. Clear the application cache to ensure the new environment takes effect:
php bin/console cache:clear --env=prod
4. Verify that debug mode is disabled by checking that APP_DEBUG is set to 0 or false.
5. Test the application to confirm that generic error pages are displayed instead of detailed stack traces.
Note: Ensure proper error logging is configured so that errors are captured in log files for debugging purposes without exposing them to end users.
