"The version of OpenJDK installed on the remote host is 8 prior to 8u472 / 11.0.0 prior to 11.0.29 / 17.0.0 prior to
17.0.17 / 21.0.0 prior to 21.0.9 / 25.0.0 prior to 25.0.1. It is, therefore, affected by multiple vulnerabilities as
referenced in the 2026-01-20 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: 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)

  - A Blind Server-Side Request Forgery (SSRF) vulnerability exists in Oracle Java 21. The vulnerability,
    which leads to Denial of Service (DoS), is present in the x509 certificate path validation mechanism when
    the non-default system property com.sun.security.enableAIAcaIssuers is set to true. (CVE-2026-21945)

  - 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: 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 of this vulnerability can result in unauthorized
    ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE, Oracle GraalVM
    for JDK, Oracle GraalVM Enterprise Edition. 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-2026-21945)

  - 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: 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 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-2026-21933)

  - 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)
