Attackers Exploit Critical Langflow and Rails Flaws in Credential-Probing and C2 Activity

Threat actors are actively exploiting critical vulnerabilities in Langflow and Ruby on Rails to conduct credential-probing and command and control activities. CVE-2026-0768 in Langflow has a CVSS score of 9.8 and allows arbitrary Python code execution as the root user through insufficient input validation. A second critical flaw in Rails, CVE-2026-66066, is also being targeted in the campaign.

Why it matters: Organizations running Langflow or Ruby on Rails face immediate risk of code execution and credential theft; patch these critical vulnerabilities and hunt for exploitation indicators in your environment today.
