CVE-2024-37014Public exploitNetwork attack vector

Authenticated remote code execution via submitted Python

Published Jun 10, 2024 · Updated Aug 2, 2024

Code injection in Langflow before 1.0.15 allows remote authenticated users to execute arbitrary code through the custom-component API. POST /api/v1/custom_component passes submitted raw_code.code directly to CustomComponent, which evaluates the Python while building its template. A low-privilege Langflow session and network access to that endpoint are sufficient; the code runs with the server process's permissions, enabling data theft or service disruption.
