  - Spring MVC applications using the functional web framework are vulnerable to stream corruption when using
    Server-Sent Events (SSE). An attacker with control over data that will be streamed to other users of the
    application might corrupt the stream of data sent to those users. Depending on the frontend application logic,
    this could corrupt state or present malicious information to other users. (CVE-2026-59313)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
