Active Exploitation of Critical Langflow RCE and Ruby on Rails Flaws
- Engineer — Act: CVE-2026-0768 in Langflow is a CVSS 9.8 RCE running as root with a public PoC and confirmed active exploitation — patch or take Langflow offline immediately; also audit Rails deployments for CVE-2026-66066 exposure and apply the latest Rails patch given the 0.28 EPSS and available PoC.
- SOC/IR — Act: Active exploitation includes credential-probing and C2 callback activity — hunt for anomalous outbound connections and lateral movement originating from Langflow or Rails app servers since these flaws became public, and build detections for post-exploitation behavior on those hosts.
