CVE-2026-65311Network attack vector

Unauthenticated audit-log suppression via configuration endpoint

Published Jul 31, 2026 · Updated Jul 31, 2026

Missing authentication in the HTTP server of ANDRITZ HIPASE-250 7.20 and earlier allows remote attackers to suppress audit logs. An undocumented logging-configuration endpoint accepts unauthenticated requests that change the server logging level and output target. Network access to the HTTP service is sufficient to disable audit output, allowing other activity to proceed without the affected logs.
