getgrav — Vulnerabilities & Security Advisories 187

GetGrav is a flat-file CMS designed for developers seeking a modern, flexible alternative to database-driven platforms. Its architecture eliminates traditional SQL dependencies, relying instead on YAML configuration and Markdown content. However, this design has historically exposed the platform to significant security risks, resulting in forty-seven recorded CVEs. Common vulnerability classes include Remote Code Execution (RCE), Cross-Site Scripting (XSS), and privilege escalation flaws, often stemming from inadequate input validation or insecure file handling mechanisms. Notable incidents have highlighted weaknesses in plugin ecosystems and core update processes, allowing attackers to execute arbitrary code or bypass authentication. While the flat-file structure offers performance benefits, it has also introduced unique attack vectors related to file permissions and serialization. Users must prioritize rigorous plugin auditing and timely patching to mitigate these persistent threats inherent in the system’s evolving codebase.
