CVE-2026-61524Public exploitNetwork attack vectorHinoki check available

Administrator-level code execution via crafted module archive

Published Aug 3, 2026 · Updated Aug 3, 2026

Unrestricted file upload in WebsiteBaker CMS before 2.13.10 allows remote authenticated users to execute code through module installation. The module installer accepts a ZIP containing valid info.php metadata and a PHP webshell, then extracts both into the web-accessible modules directory. Administrator access is required to upload the archive; direct HTTP access to the extracted webshell then executes code with the web server's privileges.
