  - 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. (CVE-2025-53057)

  - 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. (CVE-2025-53066)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 21.0.8 and
    25; Oracle GraalVM for JDK: 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 update, insert or delete access to some of 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. (CVE-2025-61748)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: RMI). Supported versions that are affected are Oracle Java SE: 8u471,
    8u471-b50, 8u471-perf, 11.0.29, 17.0.17, 21.0.9, 25.0.1; Oracle GraalVM for JDK: 17.0.17 and 21.0.9;
    Oracle GraalVM Enterprise Edition: 21.3.16. 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
    update, insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM
    Enterprise Edition accessible data as well as unauthorized read access to a subset of 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. (CVE-2026-21925)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: AWT, JavaFX). Supported versions that are affected are Oracle Java SE: 8u471,
    8u471-b50, 8u471-perf, 11.0.29, 17.0.17, 21.0.9, 25.0.1; Oracle GraalVM for JDK: 17.0.17 and 21.0.9;
    Oracle GraalVM Enterprise Edition: 21.3.16. 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 require human interaction from a person other than
    the attacker and while the vulnerability is in Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM
    Enterprise Edition, attacks may significantly impact additional products (scope change). 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 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. This vulnerability does not apply to Java
    deployments, typically in servers, that load and run only trusted code (e.g., code installed by an
    administrator). (CVE-2026-21932)
