CVE-2026-61523: Code injection vulnerability

WebsiteBaker CMS before 2.13.10 contains a code injection vulnerability in the Droplets editor that allows authenticated administrators to inject arbitrary PHP code by submitting malicious content through the droplet Code field, which is written verbatim to a publicly accessible PHP file with no content sanitization. Attackers can save a PHP webshell via the save_droplet handler to a predictable path inside the modules directory, enabling unauthenticated users to achieve remote code execution by making direct HTTP requests to the written file.
