What is CVE-2026-41459?

Xerte Online Toolkits versions 3.15 and earlier are susceptible to an information disclosure flaw that permits unauthorized users to obtain the complete server-side filesystem path of the application root. By issuing a GET request to the /setup endpoint, attackers can exploit this vulnerability to retrieve the root_path value from the HTML response. This exposure can lead to further security issues, such as relative path traversal attacks in the connector.php file, potentially compromising system integrity and confidentiality.
