CVE-2026-11340Network attack vector

Authenticated queue disclosure via missing permission check

Published Jul 7, 2026 · Updated Jul 7, 2026

Missing authorization in HAVELSAN Liman MYS before release.master.1107 allows remote authenticated users to list server installation queues. QueueController returned install-type queue records without checking the caller's server_details permission; the corrective commit adds that check. The operation requires a low-privilege API session; the patch proves unauthorized queue disclosure, but public sources do not explain additional integrity or availability effects.
