CVE-2026-41268

Flowise: Flowise Parameter Override Bypass Remote Command Execution

Published Apr 23, 2026 CVSS 3.1 · 9.8 Critical EPSS 17.4% KEV · Not listed
Description
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, Flowise is vulnerable to a critical unauthenticated remote command execution (RCE) vulnerability. It can be exploited via a parameter override bypass using the FILE-STORAGE:: keyword combined with a NODE_OPTIONS environment variable injection. This allows for the execution of arbitrary system commands with root privileges within the containerized Flowise instance, requiring only a single HTTP request and no authentication or knowledge of the instance. This vulnerability is fixed in 3.1.0.
