    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: 8u481,
    8u481-b50, 8u481-perf, 11.0.30, 17.0.18, 21.0.10, 25.0.2, 26; Oracle GraalVM for JDK: 17.0.18 and
    21.0.10; Oracle GraalVM Enterprise Edition: 21.3.17. Difficult to exploit vulnerability allows
    unauthenticated attacker with logon to the infrastructure where Oracle Java SE, Oracle GraalVM for JDK,
    Oracle GraalVM Enterprise Edition executes to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle
    GraalVM Enterprise Edition.  Successful attacks of this vulnerability can result in  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. CVSS 3.1 Base Score 2.9 (Confidentiality impacts).  CVSS Vector:
    (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N). (CVE-2026-22007)

    Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: JGSS).  Supported versions that are affected are Oracle Java SE: 8u481,
    8u481-b50, 8u481-perf, 11.0.30, 17.0.18, 21.0.10, 25.0.2, 26; Oracle GraalVM for JDK: 17.0.18 and
    21.0.10; Oracle GraalVM Enterprise Edition: 21.3.17. 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 require human interaction from a
    person other than the attacker. 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 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). CVSS 3.1 Base Score 5.3 (Confidentiality impacts).  CVSS
    Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N). (CVE-2026-22013)
