Bottom line: CISA classifies an actively exploited RCE vulnerability in Langflow as critical and orders patching for federal systems.
The US cybersecurity agency CISA has ordered US government agencies to patch an actively exploited remote code execution flaw in the Langflow framework for developing AI agents as a matter of highest priority.
The Cybersecurity and Infrastructure Security Agency (CISA) issued a directive on Tuesday requiring US government agencies to remediate an actively exploited vulnerability in Langflow — a visual framework for developing AI agents — with the highest priority. The Langflow framework is used to construct and manage automated AI systems.
The RCE (Remote Code Execution) vulnerability allows attackers to execute arbitrary code on affected systems. Since the vulnerability is already being actively exploited in the wild, CISA classifies it as an immediate threat to federal infrastructure.
For organizations outside the federal government, this means that private enterprises and institutions using Langflow should also identify and remediate this vulnerability on their systems in a timely manner. It is advisable to immediately check whether Langflow is in use in your own IT environment and what version is installed.
