Official Description
Flowise is a drag & drop user interface to build a customized large language model flow.

CVE-2026-41274 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
