"The version of OpenJDK installed on the remote host is 8 prior to 8u502 / 11.0.0 prior to 11.0.32 / 17.0.0 prior to
17.0.20 / 21.0.0 prior to 21.0.12 / 25.0.0 prior to 25.0.4 / 26.0.0 prior to 26.0.2. It is, therefore, affected by
multiple vulnerabilities as referenced in the 2026-08-18 advisory.

Please Note: Java CVEs do not always include OpenJDK versions, but are confirmed separately by Tenable using the patch
versions from the referenced OpenJDK security advisory.

  - 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. (CVE-2026-61308)

  - Vulnerability in Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE:
    25.0.4 and 26.0.2. Easily exploitable vulnerability allows unauthenticated attacker with network access
    via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result
    in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE.
    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-2026-70906)

  - 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.
    (CVE-2026-70907)

  - 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.
