Nginx remediation for vulnerability CVE-2025-54236

[lfluvisotto]

Description (*)

This pull request introduces an additional security mitigation related to CVE-2025-54236.

It was identified that the /media/customer_address/ directory may be publicly accessible, which could expose sensitive files and increase the risk of exploitation.

To reduce the attack surface, this change recommends restricting direct access to this directory at the web server level by adding the following configuration to nginx.conf

This mitigation provides a defense-in-depth layer and helps prevent unauthorized access to sensitive resources. It does not replace applying official security patches but complements them.
