  - Vulnerability in Oracle Java SE (component: Compiler). Supported versions that are affected are Oracle
    Java SE: 21.0.6, 24; Oracle GraalVM for JDK: 21.0.6 and 24. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE.
    Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to
    some of Oracle Java SE accessible data as well as unauthorized read access to a subset of Oracle Java SE
    accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g.,
    through a web service which supplies data to the APIs. This vulnerability also applies to Java
    deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets,
    that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox
    for security. (CVE-2025-30691)

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