Overview
flowise is a Flowiseai Server
Affected versions of this package are vulnerable to Arbitrary Code Injection via the customReadCSVFunc process. An attacker can execute arbitrary code on the server by supplying malicious input that is interpolated and executed without proper sanitization. This is only exploitable if the attacker is authenticated or can bypass authentication by providing the "x-request-from: internal" header when FLOWISE_USERNAME and FLOWISE_PASSWORD are not set.
