{"id":"CVE-2026-46444","aliases":["GHSA-hmg2-jjjx-jcp2"],"url":"https://o3.security/vulnerability/CVE-2026-46444","summary":"Flowise: Vector Store No Permission Checks","details":"### FINDING 4: OpenAI Assistants Vector Store - No Auth on CRUD Operations\n**Severity**: HIGH (CVSS ~8.1)\n**Type**: CWE-306 (Missing Authentication for Critical Function)\n**File**: `packages/server/src/routes/openai-assistants-vector-store/index.ts`\n\n**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.\n\nThe real issue is that the routes have no `checkAnyPermission()` middleware, meaning any authenticated user regardless of role can:\n- Create vector stores\n- Upload files to vector stores\n- Delete vector stores and files\n- Modify any vector store\n\n**Evidence**:\n```typescript\n// No permission middleware on any route\nrouter.post('/', controller.createAssistantVectorStore)          // No permission check\nrouter.put(['/', '/:id'], controller.updateAssistantVectorStore) // No permission check\nrouter.delete(['/', '/:id'], controller.deleteAssistantVectorStore) // No permission check\nrouter.post('/:id', getMulterStorage().array('files'), controller.uploadFilesToAssistantVectorStore) // No permission check\n```\n\n**Impact**: Any authenticated user can manipulate OpenAI vector stores, upload malicious files, delete data, or exfiltrate stored documents regardless of their assigned permissions.","published":"2026-06-08T15:25:24.883Z","modified":"2026-08-12T03:51:33.376746858Z","cvss":null,"epss":{"score":0.00328,"percentile":0.25517,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.2"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise%403.1.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46444.json"},{"type":"ADVISORY","url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-hmg2-jjjx-jcp2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46444"},{"type":"PACKAGE","url":"https://github.com/FlowiseAI/Flowise"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:33.376746858Z"}}
