CVE-2026-100608 · Severity: high · CVSS 8.3 · Published 2026-09-26

Flowise, an AI workflow and chatbot platform, fails to enforce proper access control on its job queue dashboard when run in queue mode.

Technical details

The /admin/queues endpoint uses only JWT authentication via verifyTokenForBullMQDashboard middleware but performs no role, permission, or workspace/organization scoping checks. Any authenticated user gains access to the full Bull-Board UI and all queued job payloads across all instances, including incomingInput, credential IDs, chatflow.flowData with custom JavaScript code, and originating tenant identifiers. The endpoint lies outside the /api/v1/* protected tree and write actions (retry, remove, promote, clean) are cross-tenant enabled.
