Flatcore

Flatcore is a small, focused content management system vendor whose product portfolio occupies a prominent niche among web publishing platforms. The vendor's vulnerability profile concentrates in its core CMS offering and recurs through application-layer input-handling and code-generation weaknesses: cross-site scripting, SQL injection, unrestricted file uploads, cross-site request forgery, and code injection flaws that are characteristic of web-facing administrative interfaces. These weakness classes align with the attack surface of a publicly accessible, user-configurable publishing system, where input validation boundaries and template rendering are critical control points. The vendor's disclosures have an elevated tendency to acquire public exploit code, reflecting the accessibility and appeal of CMS platforms to both security researchers and malicious actors. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
