Описание

Vulnerability in Oracle Java SE (component: Compiler). Supported versions that are affected are Oracle Java SE: 25.0.4.1 and 27. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Java SE 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).

A flaw was found in OpenJDK's Compiler component. An unauthenticated remote attacker could exploit this vulnerability by submitting specially crafted data to exposed compiler Application Programming Interfaces (APIs), such as through a web service. Successful exploitation allows unauthorized read access to accessible data, resulting in information disclosure.

Отчет

Red Hat has evaluated this vulnerability as having a Low impact because successful exploitation requires high attack complexity, unusual application architecture, and is constrained to limited data exposure. In standard production deployments, Java runtime environments do not expose internal compilation interfaces directly to untrusted network requests. Furthermore, potential exploitation cannot manipulate system state or cause denial of service, confining the blast radius exclusively to unauthorized read access of a restricted subset of process memory.
