CVE-2025-8943 · Unsupervised OS command execution leads to remote code execution by unauthenticated network attackers
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
The Custom MCPs feature is designed to execute OS commands, for instance, using tools like `npx` to spin up local MCP Servers. However, Flowise's inherent authentication and authorization model is minimal and lacks role-based access controls (RBAC). Furthermore, in Flowise versions before 3.0.1 the default installation operates without authentication unless explicitly configured. This combination allows unauthenticated network attackers to execute unsandboxed OS commands.
