    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: 8u501,
    11.0.32, 17.0.20, 21.0.12, 25.0.4, 26.0.2; Oracle GraalVM for JDK: 17.0.20 and  21.0.12; Oracle GraalVM
    Enterprise Edition: 21.3.19. 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 read access to a
    subset of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note:
    This vulnerability can only be exploited by supplying data to APIs in the specified Component without
    using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS
    3.1 Base Score 3.7 (Confidentiality impacts).  CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N). (CVE-2026-60589)

    Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Networking).  Supported versions that are affected are Oracle Java SE: 8u501,
    11.0.32, 17.0.20, 21.0.12, 25.0.4, 26.0.2; Oracle GraalVM for JDK: 17.0.20 and  21.0.12; Oracle GraalVM
    Enterprise Edition: 21.3.19. Difficult to exploit vulnerability allows unauthenticated attacker with
    network access via HTTP to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise
    Edition.  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 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 6.8
    (Confidentiality impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N). (CVE-2026-61308)

    Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: JSSE).  Supported versions that are affected are Oracle Java SE: 8u501,
    11.0.32, 17.0.20, 21.0.12, 25.0.4, 26.0.2; Oracle GraalVM for JDK: 17.0.20 and  21.0.12; Oracle GraalVM
    Enterprise Edition: 21.3.19. Easily exploitable vulnerability allows unauthenticated attacker with network
    access via TLS to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of
    service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note:
    This vulnerability can only be exploited by supplying data to APIs in the specified Component without
    using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS
