CISA KEV: Langflow, N-central, Apache Tomcat actively exploited

Thu, 06 Aug 2026 13:03:19 +0000

Engineer — Act: All three products are KEV-listed with confirmed active exploitation and a 72-hour federal patch deadline — check your inventory for Langflow, N-able N-central, and Apache Tomcat instances and apply vendor patches immediately, prioritizing any internet-exposed deployments.
SOC/IR — Act: Actively exploited RMM (N-central) and Java servlet (Tomcat) instances are high-value footholds; hunt for web shells on Tomcat endpoints and audit N-central for unauthorized agent activity or lateral-movement artifacts since the CISA advisory date.
Leader — Plan: Confirm with engineering whether the organization runs Langflow, N-able N-central, or Apache Tomcat and ensure the patch sprint is underway; the federal 3-day deadline signals regulator attention and may surface in upcoming audit or customer questionnaire conversations.
