Threat actors are exploiting a critical security flaw in Langflow, according to an alert<\/a> from Previdian.<\/p>\n

Langflow is an open-source platform that allows developers to build artificial intelligence (AI) applications and agentic workflows. In February 2025, DataStax, the parent company of Langflow, was acquired<\/a> by IBM.<\/p>\n

The vulnerability in question is CVE-2026-105740<\/strong> (CVSS score: 9.9), a case of authenticated remote code execution impacting versions prior to 1.9.0.<\/p>\n

\u00abAny authenticated Langflow user can achieve Remote Code Execution (RCE) on the server by adding an MCP server with the ‘stdio’ transport,\u00bb reads an advisory released<\/a> last month.<\/p>\n

\u00abThe user-supplied command field is passed directly to bash -c \u00abexec {command}\u00bb with zero validation, no allowlisting, and no sandboxing. The command executes immediately when the server list is fetched. Additionally, the env field allows arbitrary environment variable injection (e.g., LD_PRELOAD, PATH override).\u00bb<\/p>\n

\"Cybersecurity\"<\/a><\/div>\n<\/div>\n

The crux of the vulnerability is that Langflow accepts a user-provided command without restricting it to approved executables. This, in turn, can lead to shell execution.<\/p>\n

In a hypothetical attack scenario, a bad actor can exploit the flaw in the following fashion –<\/p>\n
