Summary

CVE-2026-67622 affects Flowise through 3.1.4 in its OpenAI Assistants integration. An authenticated attacker can supply an arbitrary credential UUID to Assistants endpoints, and because the credential lookup lacks a workspace ownership check, the attacker can reach credentials in other workspaces. The flaw also lets the attacker enumerate cross-workspace assistant metadata, retrieve file and vector store listings, and upload files into victim workspaces.
