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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=1.4.3
- Affected versionversion=<= 1.4.3
