Overview

flowise is a Flowiseai Server

Affected versions of this package are vulnerable to External Control of File Name or Path via the S3 Directory loader process. An attacker can write arbitrary files to locations outside the intended temporary directory by supplying crafted S3 object keys containing traversal sequences, leading to potential overwrite of application data, secrets, or configuration files. This can be exploited by an authenticated user with the documentStores:preview-process role who points the loader to an attacker-controlled S3-compatible endpoint.
