What is CVE-2026-100609?
CVE-2026-100609 is a high-severity missing authorization vulnerability in FlowiseAI Flowise, published on 26 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Flowise (npm packages `flowise` and `flowise-components`) through 3.1.4 looks up credentials by ID without filtering on the requesting user's workspace (findOneBy({ id: credentialId }) with no workspaceId condition) in several code paths: getAllOpenaiAssistants/getSingleOpenaiAssistant (GET /api/v1/openai-assistants and /api/v1/openai-assistants/:id), uploadFilesToAssistant (POST /api/v1/openai-assistants-file/upload/), deleteAssistant (DELETE /api/v1/assistants/:id, reachable by first importing a poisoned assistant row via POST /api/v1/export-import/import), and the shared helper used by getVoices (GET /api/v1/text-to-speech/voices). An authenticated user of one workspace can supply a credential UUID belonging to another workspace, causing the server to decrypt and use that workspace's OpenAI or ElevenLabs API key on the attacker's behalf. No patched version was available at the time of publication.
Weakness: CWE-639
