Decision summary

What security teams need to know first

Direct answers before the deeper technical record.

What it is

GHSA-4PWQ-XW7J-M297 is an unauthenticated vulnerability tracked by KEV Intelligence. Flowise before 3.0.6 contains an arbitrary file read vulnerability in the chatId parameter of the /api/v1/get-upload-file and...

Is it exploited?

Yes. KEV Intelligence sensors observed exploitation attempts with confirmed confidence.

Who is affected?

Affected versions: affected before 3.0.6.

What should we do?

Patch immediately, validate internet-facing exposure, and monitor for matching requests.

Overview

Arbitrary File Access

Flowise before 3.0.6 contains an arbitrary file read vulnerability in the chatId parameter of the /api/v1/get-upload-file and /api/v1/openai-assistants-file/download endpoints. The chatId value is not validated and is passed to streamStorageFile(), where a fallback file-lookup path constructed without the orgId is evaluated after the storage-directory containment check, allowing path traversal beyond the intended storage directory.

Unauthenticated attackers can read sensitive files such as /root/.flowise/database.sqlite, exposing all database content in the default configuration.
