CVE-2025-55740

nginx-defender is a high-performance, enterprise-grade Web Application Firewall (WAF) and threat detection system engineered for modern web infrastructure. This is a configuration vulnerability affecting nginx-defender deployments. Example configuration files config.yaml and docker-compose.yml contain default credentials (default_password: "change_me_please", GF_SECURITY_ADMIN_PASSWORD=admin123). If users deploy nginx-defender without changing these defaults, attackers with network access could gain administrative control, bypassing security protections. The issue is addressed in v1.5.0 and later.
