CISA Orders U.S. Federal Agencies to Urgently Patch a Vulnerability in Langflow

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to make it a priority to fix a vulnerability in Langflow — a visual framework for building AI agents. The agencies have been given until Friday to apply the fix.

The flaw in question allows attackers to bypass authentication. According to CISA, it is already being actively exploited by threat actors, which is what prompted its addition to the Known Exploited Vulnerabilities catalog and the imposition of a strict remediation deadline for federal entities.

Langflow is a platform with a visual interface designed for developing and deploying applications based on AI agents. Tools of this kind have gained widespread popularity amid growing corporate interest in bringing generative artificial intelligence into workflows.

CISA's requirement applies to U.S. federal civilian executive branch agencies, for which compliance with such directives is mandatory. This is standard practice for the agency: when actively exploited vulnerabilities are discovered in widely used software, it sets specific deadlines for mitigating the risks to government systems.

The Langflow case reflects a broader trend — as tools for building AI agents spread across corporate and government infrastructure, they are increasingly becoming targets for attacks. Organizations using Langflow, including private companies, are advised to review the details of the vulnerability and install the corresponding update as soon as possible, without waiting for mandatory directives.
