Title
Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints
Summary
IBM Langflow OSS 1.0.0 through 1.10.1 can allow an authenticated attacker to exploit the SaveToFile component to read and modify another user's uploaded files by specifying absolute paths pointing to victim storage locations. In append mode, the attacker's workflow reads victim file contents, appends attacker-controlled data, and uploads a copy containing victim data to the attacker's namespace (confidentiality breach). In overwrite mode, the attacker can replace victim file contents with arbitrary data (integrity breach). This breaks the storage ownership boundary between users.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
