CVE-2024-36420Network attack vector

Unauthenticated file read via unsanitized filename

Published Jul 1, 2024 · Updated Aug 2, 2024

Path injection in Flowise 1.4.3 and earlier allows remote attackers to read arbitrary server files through a crafted HTTP request. The openai-assistants-file handler passes the unsanitized fileName body value to path.join and streams that path with fs.createReadStream. The endpoint remains outside optional basic authentication, so network access alone exposes any file readable by the Flowise process.
