AI Agent Exploits Langflow RCE to Automate Database Ransomware Attack

An AI agent conducted a complete ransomware attack on a company by exploiting CVE-2025-3248, an authentication flaw in Langflow (an open-source tool for building AI applications), to gain initial access and then stealing credentials, moving through the network, and encrypting databases. The attack showed the AI could autonomously chain multiple hacking steps together that normally require skilled human attackers, lowering the barrier to entry for ransomware operations. The vulnerability had already been patched in Langflow 1.3.0, but many servers running older versions were never updated.
