    CVE-2025-53057:
    Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Security).  Supported versions that are affected are Oracle Java SE: 8u461,
    8u461-perf, 11.0.28, 17.0.16, 21.0.8, 25; Oracle GraalVM for JDK: 17.0.16 and  21.0.8; Oracle GraalVM
    Enterprise Edition: 21.3.15. Difficult to exploit vulnerability allows unauthenticated attacker with
    network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM
    Enterprise Edition.  Successful attacks of this vulnerability can result in  unauthorized creation,
    deletion or modification access to critical data or all Oracle Java SE, Oracle GraalVM for JDK, Oracle
    GraalVM Enterprise Edition 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. CVSS 3.1 Base Score 5.9 (Integrity impacts).  CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N).

    CVE-2025-53066:
    Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: JAXP).  Supported versions that are affected are Oracle Java SE: 8u461,
    8u461-perf, 11.0.28, 17.0.16, 21.0.8, 25; Oracle GraalVM for JDK: 17.0.16 and  21.0.8; Oracle GraalVM
    Enterprise Edition: 21.3.15. Easily exploitable vulnerability allows unauthenticated attacker with network
    access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM
    Enterprise Edition.  Successful attacks of this vulnerability can result in  unauthorized access to
    critical data or complete access to all Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise
    Edition 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. CVSS 3.1 Base Score 7.5 (Confidentiality impacts).  CVSS Vector:
    (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
