Flowise npm Package RCE Vulnerability Under Investigation
An early warning has been issued regarding a critical vulnerability in the Flowise npm package, which reportedly allows authenticated users to execute arbitrary JavaScript, leading to potential remote code execution on the server host.
What happened
The vulnerability, tracked as GHSA-9RVC-VF7M-PGM2, appears to enable authenticated users to submit arbitrary JavaScript through the POST /api/v1/node-custom-function endpoint. This can lead to remote code execution on the server host due to an escape of the NodeVM sandbox, allowing system command execution.
Professional software engineers using Flowise are advised to upgrade to the latest version that patches this vulnerability. Additionally, it is recommended to review any custom JavaScript executions within their applications to assess potential exposure.
The primary source for this vulnerability is the GitHub Advisory Database, which provides further details on the reported authenticated host RCE and NodeVM sandbox escape. For the most accurate and up-to-date information, consult the primary sources directly.
