    Directory Traversal

    Affected versions of this package are vulnerable to Directory Traversal via the upload_user_file function. An attacker can overwrite or create files in arbitrary locations on the filesystem by submitting specially crafted filenames containing path traversal sequences in the multipart form data.

    Missing Authorization

    Affected versions of this package are vulnerable to Missing Authorization via the download_image endpoint. An attacker can access and download image files belonging to any flow by knowing or guessing the flow ID and file name.

    Cross-site Scripting (XSS)

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the /api/v1/files/images/{flow_id}/{file_name} endpoint, which serves SVG files with the image/svg+xml content type without sanitizing their content. An attacker can execute arbitrary JavaScript in the context of another user's session by uploading a crafted SVG file, potentially allowing theft of authentication tokens stored in cookies, including JWT access and refresh tokens.

    Missing Authorization

    Affected versions of this package are vulnerable to Missing Authorization via the logs and logs-stream endpoints. An attacker can access sensitive application log data by authenticating with basic user privileges, as these endpoints do not enforce privilege checks.

    Arbitrary Code Injection

    Affected versions of this package are vulnerable to Arbitrary Code Injection through the Agentic Assistant validation process. An attacker can execute arbitrary server-side Python code by supplying input that causes the assistant to return malicious component code, which is then instantiated during validation.

    Directory Traversal

    Affected versions of this package are vulnerable to Directory Traversal via the download_profile_picture function in the /profile_pictures/{folder_name}/{file_name} endpoint, where the folder_name and file_name parameters are not properly filtered. An attacker can access sensitive files outside the intended directory by supplying crafted path traversal sequences, potentially allowing them to obtain authentication secrets and gain unauthorized access.

    Missing Authorization

    Affected versions of this package are vulnerable to Missing Authorization via the download_image endpoint, which allows unauthenticated access to image files by accepting flow_id and file_name as path parameters without verifying user authentication or ownership. An attacker can access sensitive image files belonging to other users by sending crafted requests with valid identifiers.

    Deserialization of Untrusted Data

    Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the disk cache service. An attacker can execute arbitrary code by supplying crafted data that is deserialized without proper validation.

    There is no fixed version for langflow-base.

    Origin Validation Error

    Affected versions of this package are vulnerable to Origin Validation Error via an overly permissive CORS configuration in the refresh endpoint. An attacker can gain unauthorized access to authentication tokens and execute arbitrary code by enticing a victim to visit a malicious webpage that performs cross-origin requests with credentials.

    Note: The option was added in version 0.6.0 (used in langflow 1.6.x) to restrict allowed origins with LANGFLOW_CORS_ORIGINS. This will become the default behavior, with permissive settings (origins = *) being opt-in, in a future release.
