CVE-2025-11959Network attack vector

Authenticated private-data access via exposed files

Published Nov 11, 2025 · Updated Nov 11, 2025

Improper access control in Premierturk HYBS before 10.2025.01 allows remote authenticated users to access exposed files and private data. The public record identifies externally accessible files or directories and personal-information exposure, but does not disclose the affected endpoint or access-control operation. Low-privilege network access is required; successful exploitation supports footprinting and unauthorized functionality use, with confidentiality and integrity impact but no service interruption.
