CVE-2026-46444: CWE-862: Missing Authorization in FlowiseAI Flowise
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, all CRUD endpoints for OpenAI Assistants Vector Store have no authentication middleware and the route path /api/v1/openai-assistants-vector-store is not in WHITELIST_URLS. However, it is also not protected by the main auth middleware when accessed via API key — the route requires API key auth (not whitelisted), but no permission checks exist on any operation. This issue has been patched in version 3.1.2.
AI Analysis
Technical Summary
FlowiseAI Flowise is a drag-and-drop interface for building customized large language model flows. In versions before 3.1.2, the CRUD endpoints for the OpenAI Assistants Vector Store at the route /api/v1/openai-assistants-vector-store require API key authentication but do not enforce permission checks. The route is not whitelisted and is not protected by the main authentication middleware, resulting in missing authorization controls (CWE-862). This allows users with an API key but without proper permissions to perform unauthorized create, read, update, or delete operations on the vector store. The vulnerability was patched in version 3.1.2.
Potential Impact
The vulnerability allows unauthorized users who possess an API key to perform any CRUD operation on the OpenAI Assistants Vector Store without proper permission checks. This could lead to unauthorized data modification or deletion, potentially impacting the integrity and availability of the vector store data. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade Flowise to version 3.1.2 or later, where this missing authorization issue has been fixed. Since the vulnerability is patched in the official release, applying this update fully mitigates the risk.
