CyberPanel before 3.0.0 contains a path traversal vulnerability that allows authenticated administrators to read arbitrary files from the server filesystem by supplying unsanitized file paths to the cloudAPI ReadReport endpoint. Attackers can manipulate the reportFile parameter in the JSON request body, which is passed directly to open() in cloudManager.py without validation or allowlisting, enabling traversal to any file readable by the root-privileged CyberPanel process including credential files, SSL and SSH private keys, and JWT secret files.
