CVE-2024-4259Network attack vector

Unauthenticated user-data collection via missing authorization

Published Sep 3, 2024 · Updated Jun 3, 2026

Missing authorization in SAMPAŞ Holding AKOS services before V2.0 and V1.0.7 allows remote attackers to collect user-provided data. The public record does not identify the affected request handler or explain which authorization check is absent before the services return or accept the data. No privileges or user interaction are required, but the published impact is limited to unauthorized collection or modification of user-provided data and excludes service interruption.
