CVE-2026-79304 · Severity: medium · CVSS 6.5 · Published 2026-09-23

CyberPanel is a web hosting control panel used to manage multiple websites, email, and databases on Linux servers. An authenticated user with ownership of any domain can read arbitrary files on the server, including other sites' configuration files, database credentials, and encryption keys, by supplying a crafted file path to the file manager. This affects multi-tenant deployments where shared server instances host multiple client sites.

## Technical details

CWE-22 path traversal in the readFileContents method of /filemanager/controller endpoint. Authorization validates only domainName ownership but does not restrict the fileName parameter to that domain's home directory or canonicalize the path, allowing authenticated attackers to specify absolute or traversal paths. The application returns file contents readable by the CyberPanel process identity (typically root or www-data), with no code execution or write access.
