CVE-2026-46476: CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes in FlowiseAI Flowise
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, CustomTemplate create and update mass-assignment allows cross-workspace template takeover. This issue has been patched in version 3.1.2.
AI Analysis
Technical Summary
Flowise, a drag-and-drop interface for building customized large language model flows, had a vulnerability (CWE-915) in versions before 3.1.2. The CustomTemplate create and update operations allowed mass-assignment of attributes without proper control, enabling an attacker with some privileges to take over templates across different workspaces. This could lead to unauthorized modification or control of templates beyond the attacker's workspace boundaries. The vulnerability is addressed by an official patch in version 3.1.2.
Potential Impact
An attacker with limited privileges could exploit this vulnerability to perform cross-workspace template takeover, potentially modifying or controlling templates in other users' workspaces. This could lead to unauthorized changes in the behavior of large language model flows built using Flowise, impacting confidentiality and integrity within the affected environment.
Mitigation Recommendations
Upgrade Flowise to version 3.1.2 or later, where this vulnerability has been patched. Since the vendor has released an official fix, applying this update is the recommended remediation. No additional mitigation steps are indicated by the vendor advisory.
