CVE-2026-70475: CWE-862: Missing Authorization in FlowiseAI Flowise
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the PUT /api/v1/executions/:id endpoint in packages/server/src/routes/executions/index.ts lacks the checkAnyPermission() middleware that protects other execution endpoints. Any authenticated user, regardless of assigned permissions, can modify execution state, data, and metadata of any execution in their workspace, enabling privilege escalation and manipulation of workflow execution results. This issue is fixed in 3.1.3.
AI Analysis
Technical Summary
CVE-2026-70475 is a missing authorization vulnerability (CWE-862) in Flowise, a drag & drop interface for building large language model flows. Specifically, before version 3.1.3, the PUT /api/v1/executions/:id endpoint lacks the checkAnyPermission() middleware that protects other execution endpoints. Consequently, any authenticated user can alter execution details in their workspace regardless of assigned permissions, leading to privilege escalation and potential manipulation of workflow execution outcomes. The vulnerability is fixed in Flowise version 3.1.3.
Potential Impact
An attacker with any authenticated access can modify execution state, data, and metadata of executions in their workspace without proper authorization. This can lead to privilege escalation and unauthorized manipulation of workflow execution results, potentially undermining the integrity of the system's operations.
Mitigation Recommendations
Upgrade Flowise to version 3.1.3 or later, where the missing authorization check has been implemented to properly restrict access to the PUT /api/v1/executions/:id endpoint. No other mitigation is indicated.
