Langflow RCE Flaw Rated 9.8 Joins CISA Risk List

A critical vulnerability affecting Langflow, a popular low-code platform for developing agentic AI workflows, has been added to the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Known Exploited Vulnerabilities (KEV) Catalog. The flaw, identified as a remote code execution (RCE) bug with a CVSS severity score of 9.8, poses a significant threat to systems utilizing the tool.

Langflow has emerged as a key utility for constructing custom AI-driven processes with minimal coding. The newly listed RCE vulnerability could allow attackers to execute arbitrary commands remotely, potentially compromising sensitive systems and data. By including the flaw in its catalog, CISA is mandating that federal agencies and organizations under its purview prioritize remediation.

The move underscores growing concerns around the security of low-code AI platforms, which are increasingly integrated into enterprise workflows. Affected entities are urged to apply patches or mitigations in accordance with federal cybersecurity directives.
