mautic/core
source listedECOSYSTEM: introduced 4.4.0; fixed 4.4.16
### Summary This advisory addresses a security vulnerability in Mautic where sensitive `.env` configuration files may be directly accessible via a web browser. This exposure could lead to the disclosure of sensitive information, including database credentials, API keys, and other critical system configurations. Sensitive Information Disclosure via `.env` File Exposure: The `.env` file, which typically contains environment variables and sensitive application configurations, is directly accessible via a web browser due to missing web server configurations that restrict access to such files. This allows an unauthenticated attacker to view the contents of this file by simply navigating to its URL. ### Mitigation Update Mautic to the latest Mautic version. By default, Mautic does not use `.env` files for production data. **For Apache users:** Ensure your web server is configured to respect `.htaccess` files. **For Nginx users:** As Nginx does not inherently support `.htaccess` files, you must manually add a configuration block to your Nginx server configuration to deny access to `.env` files. Add the following to your Nginx configuration for the Mautic site: ```nginx location ~ /\

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
