Detailsinfo

A vulnerability was found in Flowise up to 3.0.5 and classified as critical. This issue affects an unknown function of the file /api/v1/chatflows. The manipulation of the argument chatId with an unknown input leads to a file inclusion vulnerability. Using CWE to declare the problem leads to CWE-73. The product allows user input to control or influence paths or file names that are used in filesystem operations. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Flowise before 3.0.6 (affected versions 2.2.8 and earlier) contains an arbitrary file access vulnerability due to missing validation that the chatflowId and chatId parameters are UUIDs or numbers in file handling operations. By supplying a path-traversal value (e.g., '../../../../../tmp') as the chatflow id, an unauthenticated attacker can use the /api/v1/chatflows endpoint (via addBase64FilesToStorage) to write arbitrary files, and the /api/v1/get-upload-file and /api/v1/openai-assistants-file/download endpoints (via streamStorageFile) to read arbitrary files. Arbitrary file write may lead to remote code execution.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2025-71334 since 06/20/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.
