CVE-2026-67622
CriticalCVSS 9.9Summary
A vulnerability in Flowise (up to 3.1.4) in the OpenAI Assistants integration allows authenticated attackers to access credentials belonging to other workspaces by supplying an arbitrary credential UUID without workspace ownership verification.
Risk Assessment
Attackers can access sensitive credentials, enumerate assistant metadata, retrieve file and vector store listings, and upload files into victim workspaces, breaking tenant isolation.
Recommendation
Upgrade Flowise to the latest patched version. Enforce workspace ownership verification on all OpenAI Assistants endpoints.
Original NVD description (English source)
Flowise through 3.1.4 contains an insecure direct object reference vulnerability in the OpenAI Assistants integration that allows authenticated attackers to access credentials belonging to other workspaces by supplying an arbitrary credential UUID to Assistants endpoints without workspace ownership verification. Attackers can enumerate cross-workspace assistant metadata, retrieve file and vector store listings, and upload files into victim workspaces by exploiting the missing workspace-scoped authorization check in the credential lookup logic.
