Certain HP OfficeJet Pro printers may expose information if Cross‑Origin Resource Sharing (CORS) is misconfigured, potentially allowing unauthorized web origins to access device resource.
CORS is disabled by default on Pro‑class devices and can only be enabled by an administrator through the Embedded Web Server (EWS). Keeping CORS disabled unless explicitly required helps ensure that only trusted solutions can interact with the device.
