  - curl's websocket code did not update the 32 bit mask pattern for each new outgoing frame as the
    specification says. Instead it used a fixed mask that persisted and was used throughout the entire
    connection. A predictable mask pattern allows for a malicious server to induce traffic between the two
    communicating parties that could be interpreted by an involved proxy (configured or transparent) as
    genuine, real, HTTP traffic with content and thereby poison its cache. That cached poisoned content could
    then be served to all users of that proxy. (CVE-2025-10148)

Note that Nessus relies on the presence of the package as reported by the vendor.");
