Primary sources: NVD · CVE.org · FIRST EPSS

GetSimple CMS is a content management system. In versions starting from 3.3.16 to 3.3.21, an authenticated user with access to the Edit component can inject arbitrary PHP into a component file and execute it via a crafted query string, resulting in Remote Code Execution (RCE). This issue is set to be patched in version 3.3.22.
