CVE-2024-8182Network attack vector

Unauthenticated server crash via upload-file input

Published Aug 27, 2024 · Updated Aug 27, 2024

Denial of service in Flowise 1.8.2 allows remote attackers to crash the server through the /api/v1/get-upload-file endpoint. The endpoint improperly handles user-supplied request input, but Tenable has not disclosed the malformed value or failing code path. No authentication is required; successful exploitation terminates the running instance without reported confidentiality or integrity impact.
