Detailsinfo

A vulnerability classified as critical was found in FlowiseAI Flowise up to 3.0.12. This vulnerability affects an unknown code block of the file /api/v1/. The manipulation with an unknown input leads to a authorization vulnerability. The CWE definition for the vulnerability is CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.0.13, Flowise trusts any HTTP client that sets the header x-request-from: internal, allowing an authenticated tenant session to bypass all /api/v1/** authorization checks. With only a browser cookie, a low-privilege tenant can invoke internal administration endpoints (API key management, credential stores, custom function execution, etc.), effectively escalating privilege. This issue has been patched in version 3.0.13.

The advisory is available at github.com. This vulnerability was named CVE-2026-30820 since 03/05/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit.
