CyberRota Analysis

AI-Generated

The FiftyOne platform prior to version 1.17.0 is vulnerable due to its unrestrictive CORS policy, allowing any website to access cross-origin responses and potentially exfiltrate sensitive files via the /media endpoint. This vulnerability could be exploited by malicious websites to read files accessible to the server process without user interaction. Organizations using FiftyOne should prioritize upgrading to version 1.17.0 or later to mitigate this risk.

Original NVD Description

FiftyOne is an open-source platform for refining high-quality datasets and visual AI models. Prior to 1.17.0, the FiftyOne App/API server in fiftyone/server/app.py and the /media route in fiftyone/server/routes/media.py unconditionally return Access-Control-Allow-Origin: *. Because the embedded server is local and unauthenticated, a malicious website visited by the user can read cross-origin responses. The /media endpoint accepts a filesystem path, allowing a drive-by page to read files accessible to the server process and exfiltrate them without additional clicks. The allowed_origins configuration and FIFTYONE_ALLOWED_ORIGINS environment variable now make cross-origin access explicit, while the default policy is same-origin. This issue is fixed in version 1.17.0.
