What is CVE-2026-112296?

FlyCms has a vulnerability that exposes a default credential setup, allowing unauthenticated remote attackers to log in as a super administrator. By using the username 'flycms' and the password 'admin123', attackers can bypass security measures. They can then access the platform by solving an image captcha at the login endpoint (/api/auth/login), gaining full control over site content, user accounts, and configuration settings. This vulnerability highlights the importance of changing default credentials and implementing robust security practices.
