What the vulnerability does

Description

HAX CMS helps manage microsite universe with PHP or NodeJs backends. Prior to version 26.0.0, an Authenticated Local File Inclusion (LFI) vulnerability in the HAXCMS saveOutline endpoint allows a low-privileged user to read arbitrary files on the server by manipulating the location field written into site.json. This enables attackers to exfiltrate sensitive system files such as /etc/passwd, application secrets, or configuration files accessible to the web server (www-data). Version 26.0.0 patches the issue.
