CVE-2026-5426 HIGH PATCH This Week

Remote code execution in Digital Knowledge KnowledgeDeliver (all versions prior to February 24, 2026) via malicious ViewState deserialization. A hard-coded ASP.NET machineKey allows unauthenticated remote attackers to bypass ViewState validation and execute arbitrary code on the server. Mandiant reported this critical deserialization vulnerability. EPSS score of 0.08% (24th percentile) suggests low observed exploitation activity, though no public exploit is confirmed at time of analysis. CVSS vector indicates network-accessible attack requiring no privileges or user interaction, but the 7.5 score reflects only Confidentiality impact-real-world RCE capability makes this significantly more severe than the partial CVSS rating suggests.
