flowisenpmDescription
FINDING 4: OpenAI Assistants Vector Store - No Auth on CRUD Operations
Severity: HIGH (CVSS ~8.1)
Type: CWE-306 (Missing Authentication for Critical Function)
File: packages/server/src/routes/openai-assistants-vector-store/index.ts
Description: ALL CRUD endpoints for OpenAI Assistants Vector Store have no authentication middleware AND the route path /api/v1/openai-assistants-vector-store is NOT in WHITELIST_URLS. However, it is also NOT protected by the main auth middleware when accessed via API key — the route requires API key auth (not whitelisted), but NO permission checks exist on any operation.
The real issue is that the routes have no checkAnyPermission() middleware, meaning any authenticated user regardless of role can:
- Create vector stores
- Upload files to vector stores
- Delete vector stores and files
- Modify any vector store
Evidence:
// No permission middleware on any route
router.post('/', controller.createAssistantVectorStore) // No permission check
router.put(['/', '/:id'], controller.updateAssistantVectorStore) // No permission check
router.delete(['/', '/:id'], controller.deleteAssistantVectorStore) // No permission check
router.post('/:id', getMulterStorage().array('files'), controller.uploadFilesToAssistantVectorStore) // No permission check
Impact: Any authenticated user can manipulate OpenAI vector stores, upload malicious files, delete data, or exfiltrate stored documents regardless of their assigned permissions.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for flowise, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update flowise to 3.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-46444 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
