Unauthenticated file disclosure via path traversal
Published Sep 7, 2026 · Updated Sep 8, 2026
Path traversal in Next4biz CSM 6.8.9 through 8.0.2 allows remote attackers to read arbitrary files from the application server. Public CNA and TR-CERT materials do not identify the vulnerable endpoint, parameter, or file-access routine, so the precise input-handling failure remains undisclosed. No authentication or user interaction is required, and the documented consequence is limited to confidentiality loss through file disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
