The Langflow remote code execution vulnerability (CVE-2026-33017) is actively exploited to deploy Monero miners and automate ransomware attacks using AI. The attacks highlight vulnerabilities in exposed AI applications and the evolving threat landscape, as AI agents can execute complex attacks independently.
The Langflow application, used for building AI apps and agent workflows, is under attack due to a remote code execution (RCE) vulnerability, CVE-2026-33017, which scores 9.3 on the CVSS scale. The flaw allows attackers to execute unauthorized Python scripts via exposed AI application endpoints, compromising enterprise networks.
Attackers exploit the Langflow vulnerability to deliver Monero cryptocurrency miners. By using malicious scripts, they gain access to systems, terminate competing miner processes, disable security controls, and establish persistence with cron jobs. This activity was mainly observed over a 19-day period from March 27 to April 15, 2026.
A separate exploit of an older Langflow flaw (CVE-2025-3248) led to the first AI-driven ransomware attack, orchestrated by an AI agent named JADEPUFFER. This attack, run by a large language model, enabled the automatic breach, credential theft, and encryption of a company's production database, showcasing a shift in ransomware capabilities.
The Langflow vulnerability has been patched in version 1.3.0. However, the incidents stress the importance of securing AI endpoints and illustrate how AI is being leveraged for autonomous operations in cyber threats. It marks a significant evolution in the landscape, where the skill requirement for running attacks is notably reduced.

Sysdig reports the first ransomware attack fully automated by an AI agent, named JADEPUFFER. Exploiting a vulnerability in Langflow, the AI managed to breach a network, steal credentials, and encrypt a production database without human intervention, indicating a significant shift in the threat landscape.
Threat actors are exploiting the Langflow RCE vulnerability (CVE-2026-33017) to deploy Monero miners on unprotected AI application endpoints. This enables broader network access and compromises systems by using a combination of malicious scripts and persistence techniques.
