CVE-2026-73098— Apache Juneau: Unsafe reflection allows attacker-controlled class initialization during parsing

Quick assessment

Affected
Apache Software Foundation Apache Juneau
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Juneau 中存在动态加载代码控制不当的漏洞。 当 Apache Juneau 将某个值解析为 类型的属性（包括泛型形式）时，其默认的类替换机制会在启用初始化的情况下加载指定类。因此，如果输入中指定了应用程序类路径上的某个类，该类的静态初始化器就会被执行。该漏洞的影响程度取决于部署环境中实际存在的类。 此问题影响 Apache Juneau 9.2.0 及之前版本。 建议用户升级至 9.2.1 版本，该版本已修复此问题。

Vulnerability Title
Apache Juneau: Unsafe reflection allows attacker-controlled class initialization during parsing
Source: CVE Program / CVE List V5
Vulnerability Description
Improper control of dynamically-loaded code vulnerability in Apache Juneau. When Apache Juneau parses a value into a property of type java.lang.Class (including parameterized forms), the default class swap loaded the named class with initialization enabled, so input naming a class on the application classpath ran that class's static initializer. The impact depends on the classes present in the deployment. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue.
