CVE-2026-8481: IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API
Summary
IBM Langflow OSS versions 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability (RCE, where attackers can run commands on a system they don't own) in the code validation API endpoint. The vulnerable endpoint accepts and directly executes user-supplied Python code without any sandboxing (isolation from the rest of the system) or input validation, allowing authenticated users to run arbitrary system commands with full server privileges.
