No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

Flowise through 2.2.4 contains an unauthenticated arbitrary file upload vulnerability in the /api/v1/attachments endpoint when storageType is set to local. Attackers can exploit path traversal in the chatId and chatflowId parameters to upload malicious files to arbitrary directories, potentially enabling remote code execution and server compromise.
