CVE-2026-18808 Sep 01, 13:20 CRITICAL Act Now

Remote code execution in Klemsan KIO (Klemsan Internet Objects) versions prior to v1.9 allows attackers to inject and execute arbitrary code against the network-facing application. The flaw, reported by TR-CERT (Turkey's national CSIRT), carries a CVSS 9.8 and requires no authentication or user interaction, giving full compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial attack profile makes it a high-priority patch.
